The Solar System
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!
4,302 Questions
Which planet is the queen of planets?
Saturn is considered the Queen of Planets according to the book named "SATURN" by the author Elaine Landau Publication 1999, pg. 16 by Franklin Watts Publishing company.
FYI- Jupiter is considered the "King" of planets in our solar system.
Which main heavenly bodies make up the solar system?
The main heavenly bodies in our solar system are the Sun, eight planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune), their moons, and dwarf planets like Pluto. The Sun is the central star around which all these bodies revolve.
Is mercury dry and have craters like the moon?
First ,the presence of craters on Mercury. Yes these are present and have been confirmed by NASA photographs. These craters are created by similar processes as those on the moon.Mercury has water ice in shadowed craters at its north pole. This was identified by radar examination of the planet in 1994 and later confirmed by NASA photographs.
Similarly water ice has been identified in shadowed craters at the moon's poles.
As a consequence:
- Mercury is not dry, it has ice deposits
- Mercury has craters formed by impacts like those on the moon.
- Some of the craters in both locations are dry (the majority) Others have ice deposits.
How big is each planet in miles?
The Body Miles at Diameter
Sun 865,370
Jupiter 86,800
Saturn 71,500
Uranus 29,500
Neptune 28,000
Earth 7,926
Venus 7,610
Mars 4,140
Pluto 3,700
Mercury 3,010
Moon 2,160
4.3 light years
===========================
Sorry. "Light year" is an answer to "how far", not "how long".
Alpha Centauri is about 4.4 light years away from our solar system and everything in it,
which means that it takes AC's light about 4.3 years to get here.
No, Pluto does not have humidity as it has a very thin atmosphere composed mostly of nitrogen, methane, and carbon monoxide. These gases do not create the conditions necessary for humidity to exist on Pluto.
What are facts about the surface of Saturn?
Saturn's surface is primarily composed of gases, without a solid surface like Earth's. It has a thick layer of clouds made up of ammonia crystals, water ice, and other substances. The planet's distinctive rings are made up of chunks of ice and rock.
The solar system is made up of eight major planets, including Earth, and five known dwarf planets, like Pluto. In addition, there are numerous other smaller objects, such as asteroids and comets, that also orbit the sun within the solar system.
What keeps the objects in the solar system in orbit around the sun?
Gravity. The sun's mass keeps all the planets in place, following the same orbit.
It is the same with the moon around the Earth and for others planets moons.
If the moon was bigger than the Earth, then earth would orbit the moon because the moon's mass is bigger.
What are principles of system theory?
Some principles of system theory include understanding systems as a whole with interconnected components, recognizing feedback loops and relationships between elements, and analyzing systems in terms of inputs, processes, and outputs. It also involves studying the dynamic behavior of systems over time and across different scales.
What is debris in the solar system called?
When the Solar System formed, not everything was used to make planets and moons, leftovers became asteroids and comets. They are perhaps the oldest remnants of the early Solar System and what we learn from them tells us about our own early history.
Most of the asteroids lie between the orbits of Mars and Jupiter, but some have very elliptical orbits which bring them very close to Earth. They range in size from about 30% the diameter of our moon to pebble sized objects. In number, there are probably billion of asteroids in the solar system.
The largest known asteroid is Ceres which was the first asteroid to be discovered in 1801. Ceres is about 1/3 the size of our moon. It can be seen in amateur telescopes if one knows where and when to look.
Most asteroids are of the small irregular variety. None of them are large enough to have high enough gravity to pull themselves into spherical shape. Images of the same asteroid vary in brightness which confirms the irregular shape.
The Galileo spacecraft passed through the asteroid belt twice on its way to Jupiter. The spacecraft passed only 16.000 km from the asteroid Gaspra in 1990 and returned excellent images. Gaspra is an oblong world measuring 20 by 12 by 11 km. It is covered by a layer of shattered soil about a meter deep. There are also numerous craters on Gaspra's surface.
In 1993, Galileo passed only 3500 km from the asteroid Ida. This was another irregularly shaped world about 52 km long. Ida is also a heavily cratered world. What was startling about Ida was that it was found to have a smaller body orbiting it! The little moon was 1.5 km in diameter, the first found to orbit an asteroid.
The asteroids which pass close to Earth are known as Near Earth Objects. They are tracked by a program called Spacewatch. The program has found over 100 times more near Earth objects than was expected. Over 50 of these objects pass within the moon's orbit each day. The danger of a collision with Earth is minimal but still significant. Astronomers are more interested in the origin of these objects.
Astronomers have divided asteroids into 3 classes, according to color and spectra. S type asteroids, including Gaspra, are reddish in color. It is believed these are silicates mixed with metals. C type asteroids are very dark in color and appear to be carbonaceous in composition. M type asteroids are bright but not reddish. These appear to be iron-nickel mixtures. S types are common in the inner asteroid belts while C types are common in the outer belts.

Saturn is the next furthest planet from the Sun after Jupiter. The order of planets is below.
- Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.
What 8 planets were known to make up the solar system before the telescope was invented?
Earth, Mercury, Venus, Mars, Jupiter, Saturn. There were six.
Since 2006 what has Pluto been classified as in the Solar System?
Pluto has been classified as a dwarf planet in the Solar System since 2006. This reclassification was made by the International Astronomical Union (IAU).
How far is the distance across the solar system to Neptune?
The distance across Neptune at its equator is 30,599 miles. This is equal to 49,244 kilometers. Neptune is the fourth largest planet.
The gas giants are: Jupiter, Saturn, Uranus and Neptune.
What are some ways that scientists are currently learning more about the solar system?
Scientists are currently using mirror telescopes in space that do not have to deal with light pollution and are more clear than lens telescopes to take pictures of the solar system. They are also using radio telescopes to try and discover extra terrestrial life.
Did the sun claim 50 percent of the solar system's matter when it formed?
No. The Sun is 99.6% of all the mass in the solar system, and half of the remainder is Jupiter.
What planets in the solar system are known to have life?
As of now, Earth is the only planet in our solar system known to have life. Scientists have not found any definitive evidence of life on other planets within our solar system, although there are ongoing investigations into the potential habitability of places like Mars and some of the moons of Jupiter and Saturn.
What instrument did Galileo develop which help find evidence to support the heliocentric theory?
Galileo developed the telescope, which allowed him to observe celestial bodies such as the moons of Jupiter and the phases of Venus. These observations provided evidence to support the heliocentric theory proposed by Copernicus.
What is the red planet in the solar system?
The red planet in our solar system is Mars. Its reddish color comes from iron oxide, or rust, on its surface. Mars is the fourth planet from the Sun and is known for its distinctive reddish appearance in the night sky.
The Earth is part of the Solar System, this includes an area of space which contains a star, planets and other bits and bobs such as meteorites and asteroids and the like.
Here's some important basic stuff
The Sun is at the centre, with 8 planets and a planetoid orbiting it (pluto was downgraded from planet to planetoid at some point). These planets, in order from the closest to the sun to the furthest, are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Neptune and Uranus. Pluto is the furthest out but again, it is no longer classed as a planet.
Between Mars and Jupiter lies the Asteroid belt, another distinguising feature and beyond Pluto is another asteroid belt called the Kupier belt but it is so sparse and spread out, if you were in it, you wouldn't see any asteroids.
Each planet is different (obviously), size, length of year/day, number of moons, weather patterns, atmosphere, there's a long list and probably more information than you could read off of wikianswers.
That's the basics, the planets of the solar system and some interesting other stuff, hope it helped because your question didn't actually make too much sense.
Explosive object in your solar system?
There are no known explosive objects within our solar system. Explosions in space are typically associated with events like supernovae in distant galaxies, rather than occurring within our own solar system.
Is Venus the prettiest planet solar system?
It is to most people since it is the planet that the Greek goddess Aphrodite owns and since Aphrodite is the goddess of beauty and love. Saturn is also considered as one of the prettiest planets due to it's rings and it's many different colors. Neptune and Uranus are also one of the prettiest. Those 4 are all on the same level. The rest of the planets are considered ugly.
