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
How far does the earth rotate in 15 minutes?
According to some scientists publications the average speed of the earth rotation is about 30km/s, so 15 minutes has to be 27000km
How does the suns size compare to other objects in the solar system?
The Sun is the largest object in our solar system, comprising about 99.8% of its total mass. By comparison, all the other objects in our solar system, including planets, moons, asteroids, and comets, make up only about 0.2% of the solar system's mass.
What are the smallest stars called in the solar system?
Mercury is the smallest actual planet of the eight comprising the solar system. It is actually smaller (but more massive) than the moons Ganymede and Titan. Mercury has about 5.5% of the mass of Earth.
Before 24 August 2006, Pluto considered the smallest planet of our solar system. On that date, the IAU modified the definition of "planet" and Pluto no longer qualified. It was reclassified as a "dwarf planet." There are a number of smaller objects, including dwarf planets, asteroids, and Kuiper Belt objects (past the orbit of Neptune).
Sizes of the Planets (largest to smallest)
Jupiter
Saturn
Uranus (3rd largest)
Neptune (3rd most massive)
Earth
Venus

Mercury
What is the first planet that is made up of heavy metals in your solar system called?
The first planet in our solar system that is primarily made up of heavy metals is Mercury. It has a large metallic core, predominantly made of iron and nickel, which is thought to make up about 60% of its mass.
Why doesn't Earths Moon Have a name like the other moons in our solar system?
I think it's name is just "The Moon".
Perhaps we are simply parochial about the matter. Our moon is, well, ours. It does have other names. Selene for instance, or Luna.
It does; it is either "The Moon" or "Luna".
However, there's no real need to NAME something if there is only one. The planets have names; even in antiquity, there were five visible planets. Thousands of visible stars have names. But there's no special name for the Sun, or the Moon, because they were (as far as they could tell) unique.
From the dawn of mankind until just a few hundred years ago (which is a very, very long time indeed), the ONLY moon in existence was "the moon." When someone talked about the moon, everyone else knew what they were talking about since it was the only one.
It was just an eyeblink ago (in historical time) that telescopes were invented and we found out there were other moons. By that time "Moon," had become our moon's name and to this date when someone says, "Look at the moon." we still look at our moon rather than some other planet's moon(s). Since for most of us, Moon, still means our moon. For astrologists, I guess they specify by saying, "Earth's moon," so other astrologists know which moon they are speaking about.
The Caloris Basin is an impact basin. It is one of the largest impact craters in the solar system.
It was created after the heavy bombardment period and is estimated to be 3.8 billion years old.
What is the three theory of the formation of the solar system?
The three theories of the formation of the solar system are the nebular theory, the planetesimal hypothesis, and the gravitational instability theory. The nebular theory proposes that the solar system formed from a rotating disk of dust and gas, while the planetesimal hypothesis suggests that small, solid bodies collided and accreted to form planets. The gravitational instability theory proposes that clumps of material in a protoplanetary disk collapsed under their gravity to form planets.
Asteroids are typically only a few metres to a few hundred metres across. The largest ones may be a few hundred km across, with the largest asteroid being a dwarf planet called Ceres (974km across.
Planets are larger than asteroids, from around 4878km across (Mercury's diameter - the smallest) to around 22,400 km in diameter (Jupiter - the largest).
The Sun is much bigger again, with a diameter of 1,392,000 km.
What planet was taken away from the solar system?
Pluto is the only one that has been taken away from the solar system for now but more planets are beginning to be argued over. Pluto was taken out because it was a moon.
How has your understanding of the solar system changed over time?
As with all branches of the sciences, as new evidence comes to light, old ideas receive revisions or are sometimes abandoned for improved ideas. It was once thought the planets and Sun orbited the Earth; later it was realized it was more accurate to say the planets orbited the Sun since that notion was more consistent with observations.
What is the Helicentric theory of the solar system?
No such thing as "helicentric"
The heliocentric theory states that the Sun (helios) is the center of the solar system (or the universe if you are talking about ancient heliocentric theories - before the knowledge of other star systems and galaxies).
Where is earth in are solo system?
Earth is the third planet from the Sun in our solar system, located between Venus and Mars. It is the only planet known to support life.
Without the Sun's gravitational force, the planets in the solar system would no longer remain in their orbits and would drift off into space. The absence of the Sun's gravity would disrupt the delicate balance of the solar system, leading to chaos and potential collisions between planets. Essentially, the solar system would cease to exist in its current form without the Sun's gravitational force.
What is the name of tenth planet in solar system?
There isn't a tenth planet in the Solar System.
There are 8 planets in the Solar System:
- Mercury
- Venus
- Earth
- Mars
- Jupiter
- Saturn
- Uranus
- Neptune
In addition to the 8 planets, there are 5 dwarf planets:
- Ceres
- Pluto
- Haumea
- Makemake
- Eris
Pluto and Ceres were once counted among the planets. Ceres became an asteroid, and was later reclassified as a dwarf planet; Pluto was a planet and was then reclassified as a dwarf planet.
Though the dwarf planets meet 2 of the 3 requirements to be a planet, they do not qualify according to the IAU definition and hence, they are not counted among the planets.
An object that is inaccurately called the 10th planet is 90377 Sedna. Sedna is a trans-Neptunian object and a likely dwarf planet discovered by Michael Brown (Caltech), Chad Trujillo (Gemini Observatory) and David Rabinowitz (Yale University) on November 14, 2003. It is currently 88 AU from the Sun, about three times as distant as Neptune.
old Mayan story and no body would believe it. As people said the end of the world will be in 2000, and nothing happend, again the stupid Mayan said the end of the world will be in 2012........ The question here is how did they know?....... do you have an answer?....no you don't, because now with everything we have and we don't know if that is true or not
Can you survive for 2 days on Neptune?
No, it is not possible for humans to survive on Neptune for even a short period of time. Neptune's atmosphere is primarily composed of hydrogen, helium, and methane, with extreme cold temperatures and high winds, making it inhospitable for human life.
How long would it take a beam of light to travel the solar system?
It takes light about 8 minutes and 20 seconds to travel from the Sun to Earth. Since the solar system spans a distance of about 4.24 light-years, it would take light approximately 4.24 years to travel from one end to the other.
How many asteroids do scientist believes exist in the solar system?
Scientists estimate that there are over 750,000 asteroids in the solar system, with the majority found in the asteroid belt between Mars and Jupiter. This number continues to grow as more are discovered through telescopic observations and space missions.
What are two classes of planets found in the solar system?
The two main classes of planets in the solar system are the terrestrial planets (Mercury, Venus, Earth, Mars) and the gas giant planets (Jupiter, Saturn, Uranus, Neptune). Terrestrial planets are rocky, dense, and relatively small, while gas giant planets are primarily composed of gases and have a much larger size compared to terrestrial planets.
Which of these is closest to the age of your solar system?
The Solar System is about 4.6 billion years old.
How is Earth different from eight planets in this solar system?
Earth is unique among the eight planets in our solar system because it is the only one known to have liquid water on its surface, supporting life as we know it. Additionally, Earth has a diverse and complex atmosphere that sustains a rich variety of ecosystems. It is also the only planet with known intelligent life forms.
Who are the scientist study the solar system?
The scientists who studies planets or heavenly bodies are astronomers.
They study by looking from the telescope at night and recording it. Afterwards, they give the information they've found.
What is the largest non planetary body in solar system?
The largest non-planetary body in the solar system is Ganymede, one of Jupiter's moons. Ganymede is even larger than the planet Mercury and is the only moon known to have its own magnetic field.
Which magnitude is brighter a negative number or a positive number?
A positive number is brighter than a negative number. Brightness in astronomy is measured in magnitudes, where smaller (negative) magnitudes represent brighter objects. Positive magnitudes are assigned to dimmer objects.
Why are objects in the solar system different from eachother?
Objects in the solar system are different from each other due to variations in size, composition, and distance from the sun. These factors influence their physical characteristics, such as shape, density, and surface features. Additionally, the processes that formed and shaped each object, such as planetary formation or impacts from other objects, contribute to their differences.
