The Solar System

Parent Category: Planetary Science
Ever wondered if there is life on Mars? Or if Jupiter has five moons? Look no further; here is the category concerning all questions about our solar system and the known planets!
Mercury's atmosphere contains small amounts of hydrogen,helium, and oxygen. It also has even tinier amounts of sodium,potassium, calcium, and magnesium. Some of the gas particles comefrom the solar wind. Others are made by radioactive decay or whenmicrometeorites smash into the surface.
There is no such thing as up and down in space, so it just revolvesaround the sun.
It doesn't mean anything in particular. The Moon is low when it isrising or setting, and always looks bigger when it's near thehorizon. This is called the Moon illusion.
Moons don't produce light.
Pluto's temperature varies with its distance from the Sun. We thinkthe maximum daytime temperature is about -223 degrees C.
On the Moon there is no atmosphere, so there is nothing to breathe.In addition we need the pressure of the air on our bodies. We alsoneed protection from the extremes of temperature found there.
As the Moon moves in its orbit around the sun, our view ofthe side illuminated by the Sun changes. Let us work through the cycle, starting with the full Moon . At full Moon , the moon rises at sunset and sets at sunrise.At 3rd quarter , the moon rises at midnight and setsat noon.

The Moon always keeps the same side facing the Earth. So, whatever direction you name, there is some place on the Moon from which the Earth appears in that direction, and if the observer doesn't move to a different place on the Moon, then the Earth doesn't move either. It's always in the same...
On the 1st, 29th and 30th of November 1860.
Yes. Mass and weight are different quantities. The mass of the astronaut is always the same everywhere. The weight of the astronaut is the force on it due to gravity, which depends on the mass and the strength of gravity at the point on the planet, moon or space station the astronaut is standing...
I'm pretty sure there are more than just 2000 moons!!!! Ouruniverse is HUGE and continues to expand everyday, so there must belike MILLIONS OF MOONS! I can't exactly give you a number of howmany moons exist in the universe, because that would take more than5 billion years. Conclusion: there are a...
Gravitation follows an inverse square law, so a gravitational fieldwhile eventually small enough to be negligible will never benon-existent.
This effect is caused by the atmosphere of the earth. The reasonfor the orange colour is due to the scattering of light by theatmosphere. When the moon is near the horizon, the moonlight mustpass through much more atmosphere than when the moon is directlyoverhead. By the time the moonlight reaches...
Not sure how scientific you want the answer to be but the first 3 things that come to this uneducated mind of mine are: 1. They both orbit another entity 2. They are both spherical in shape 3. Both have mass These 3 properties are true of many things but they technically answer the...
24,902 miles (40,075 kilometers) at the equator and 24,860 miles (40,008 kilometers) around through the poles.
About 470 million km or 292 million miles
Neptune has six rings, but they are really hard to see.
Jupiter has rings, but they are not as visible as those of Saturn.
The moon always appears larger at full moon because it is closer toEarth.
There is no starting point. We don't know where Pluto startedorbiting so we cannot determine the answer to this question.However, we do know that it takes Pluto 248 years to orbit the sun.
If the planet was exactly in between Mars and Jupiter, it wouldtake 3645.029 days.
No: it lacks a breathable atmosphere; it has no form of water on its surface (barring a small amount of polar ice); the temperature ranges across hundreds of degrees Celsius from night to day, and the extremes are well without human ability to stand unless they have some serious protective equipment...
Interesting question.. so far I have only come up with a few things of which I am not 100% sure about. + Earthquakes + Earth's orbit around the sun + The internet?
2000 miles ... then you will run into a black hole which will then take you to a portal that takes you back to your house....shortly after you will die from a hernia
Jupiter actually has no land. It is gas. This makes it sort of hardfor someone to reach Jupiter to study it. If someone where totravel to Jupiter, they wouldn't land.
The moon can rise between 6pm and 9pm.
Yes, otherwise we wouldn't be able to see them.
The Earth's rotation is, in fact, slowing. But not at a rate thatanyone would notice-unless one happens to be around in 150 millionyears. Using eclipse data from as far back as 2000 BC, scientistsestimate that the period of Earth's rotation is growing byapproximately 1.7 milliseconds per solar day...
Our solar system has a sun in the middle, planets circling the sun,moons circling the planets, and asteroids circling the sun. Thereare also comets circling the sun in a much larger orbit than theplanets.
When the Moon was in its molten stage 4.5 billion years ago,lighter aluminum-rich material floated to the surface and createdwhat we know today as the Lunar Highlands. The heavier dark basaltssank toward the center of the Moon but later percolated upwardthrough cracks and fissures that were opened...
Earth, Mercury, Venus, Mars, Jupiter, Saturn. There were six.
The Earth belongs to the terrestrial planets(Mercury, Venus, Earth,and Mars).
Almost all of the early astronauts were military (and some civilian) test pilots.
The Romans knew of seven bright objects in the sky, the sun, the moon and five brightest planets. They named them after their most important gods. Saturn was named after the Roman god of agriculture. According to myth, Saturn introduced agriculture to his people by teaching them how to farm the land...
The Moon's orbital plane is tilted about 5 degrees to the ecliptic(the Earth's orbital plane), so the Sun, the Moon and Earth do notperfectly align every new moon or full moon. We can have an eclipseonly if the alignment of the three bodies happens along theintersection of the two orbital planes.
Almost all planets in the Solar system orbit the sunanti-clockwise when viewed from the northern side, with theexception of Venus, which orbits anti-clockwise. This is due to theinitial conditions of the gas cloud that was collapsing into theplanets while our Star system was just forming.
About 71% of Earth is cover in water.
Answer 1: It is not true that dogs live seven years for every one of a human. That is but a popular myth. And any source on the net - or your veterinarian - will confirm that fact. And "dog days" refers to the hottest days of the summer, usually between July and September, and has nothing to...
Whenever it is at its perigee, i.e. its closest distance to Earth.This happens every 27,55 days, a time interval known as anAnomalistic Month. The moon perigee can vary between 356000km and370000km, so the moon's apparent size varies accordingly. However,you'd not be able to tell the difference...
One AU is 148,597,871 km, so 0.7 AU is 104,718,510 km. The velocityof light and other electromagnetic radiations in free space is299,792.458 km/second, so the time for the round trip is (2 *104,718,510 / 299,792.458) seconds - or 698.6 seconds (11 minutes,38.6 seconds.)
Very slowly. Current technology can not get a human to Uranus(alive).
no it can not the red spot on Jupiter is a giant hurricane that can destroy anything that enters it but it does not suck it in
A "Blue Moon" hence the phrase: "once in a blue moon" meaning very seldom.
The moon's average distance to Earth is about 384400km. Its closestapproach to earth brings it to 356000km. So it never really is50000km "closer to the Earth than usual" as long as you arereferring to its average distance by that.
Eris is located in the Kuiper belt [See related question] beyond the orbit of Neptune.
About 1,350,000 miles per hour or 2,175,000 kilometers per hour
Wikipedia has it at 1846 kg/ 1.846 tonnes
Yes. Because Earth spins around the sun and rotates on its axis, different parts of the world face the sun at a different time, causing day and night. +++++++ Answer ++++++++++ Your question is about the earth's orbit causing night and day. The answer for that is NO. It's the earth's rotation...
Maybe if man kind keeps being selfish greedy and unloving to most then yes, he just as well may, but then he will rebuild it, just like it noahs ark.
it wont it just depends on what the horizon is made of
The Astronaut Class of 1978, otherwise known as the "Thirty-FiveNew Guys," was NASA's first new group of astronauts since 1969.This class was notable for many reasons, including having the firstAfrican-American and first Asian-American astronauts. DuringWomen's History Month in March, NASA...
It shines becuase it reflects off the sun. But during the day it isblocked by the suns light
Earths atmosphere consists of 78.09% Nitrogen, 28.95% Oxygen and 1%trace elements, mainly Argon. The martian atmosphere consists of96% Carbon Dioxide, 1.9% Nitrogen, 1.9% Argon, with oxygen presentonly as a trace element. Where you to inhale the martian atmosphereyou would suffocate. The atmosphere...
A black dwarf would be the same size as a white dwarf: between7,000 and 17,000 miles across.
The Moon's perigee is now about 363,104 km but it is falling constanly at the rate of a few centemeters per year.
In the Solar System Saturn is 'after' Jupiter.
Saturn is the next furthest planet from the Sun afterJupiter. The order of planets is below. . Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.
To revolve around the sun, it takes 88 days. To rotate on its ownaxis, it takes 58.6 days. One rotation takes 175.97 Earth days
On 30 january, 2010, the moon closest to earth in recorded history.
Beyond the orbit of Neptune, there are uncounted numbers of small icy objects such as Pluto, Sedna, Eris, Makemake, and Haumea. They are similar to both planets and comets and are made largely of frozen gases. The term "plutoid" is also used to describe these Kuiper Belt objects (KBOs).
because the earth is spinning and as it spins the sun appears tomove.
They're considered moons. If I'm mistaking, no moons create their own light. The Sun's rays reflect off of the "small revolving body" surface and create the light we see.
Yes, "Whenever the sun is shining in your town" is a fragment. Itdoes not complete the thought. Some examples of a complete sentence would be: . Whenever the sun is shining in your town, the children come outto play. . Whenever the sun is shining in your town, the road is too hotto walk on. ....
it may cause an earth quake
A penumbral lunar eclipse takes place when the Moon moves throughthe faint, outer part of the Earth's shadow.
Jupiter is Gaseous Planet so no Lander/Rover can land on Jupiter.Voyager is basically a Spacecraft and spacecraft is used as flybyaround a planet or object. It had a flyby of Jupiter in1979. It is now outside the heliopause - the "bubble" of plasmacoming from the sun otherwise known as solar wind....
Neptune's and Earth's orbits place them at different distances at different times. The approximate minimum distance between the two is about 4.3 billion kilometers, and the approximate maximum distance between the two is about 4.7 billion kilometers.
Triton, proteus, Nereid, Larissa, and Galatea, according todiameter
If you've ever heard of the expression "once in a blue moon", you would probably refer to it as being "rare" or "unusual", so if you were born on a blue moon (which I have just found out I was) it means you're pretty unique!
Venus will also have an eclipse
If by "causes" you mean what caused Earth to form - Earth wasformed from the left over stuff that formed Sun. A nebula of dustand rocks was pulled together by its own gravity and formed thesun, but not all of it was pulled to the center of the mass and theresidual stuff began to orbit around the Sun...
Anything which is part of the normal landscape or sky (trees,hills, birds,clouds, planes) usually looks smaller when they'renear the horizon. The reason for this is simple: stuff near thehorizon is generally more distant. Just take trees in thelandscape, or a road disappearing in the distance as an...
The sun has amagnetic field that gets twisted around inside the sun as it spins.There are places on the sun where this magnetic field rises up frombelow the sun's surface and pokes through, creating sunspots . Sunspots are magnetic and often have a north and south pole like a magnet. hope this...
Mankind has not yet gone to Neptune nor a satellite. There are onlysatellites around the Earth, Moon, Venus, Mars, We have sent anunmanned probe to Neptune (Voyager 2), but it did not go intoorbit. It just flew by and took some pictures.It would have takenfar too much energy to slow the probe down...
No. Reasons are: 1> Atmosphere temperature is too low. 2> Pressure is too low. 3> Water samples found does not mean there is adequate water or adequate Oxygen. 4> You do not have market to buy food. 5> You do not have that on Mars what we call here natural resources & minerals. 6> Many more ...........
Yes. But it also orbits the Earth counterclockwise (west-to-east)which slightly slows its "apparent motion" east to west. The Moonwill appear in the sky longer than the background stars around it.
