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
What is the correct definition of a model?
A scientific model is simply an idea that allows us to create
explanations of how we think some part of the world works.
That is the basic definition for it.

What is the farthest place in the Solar System that humans have visited?
The farthest place in the Solar System that humans have visited is the Moon. The Apollo missions carried astronauts to the Moon's surface, with Apollo 17 traveling the farthest distance from Earth of any human-crewed mission.
What is the cloud that surrounds the solar system?
The Oort Cloud is a region of space surrounding our solar system that is believed to contain trillions of icy objects, such as comets, extending out to about 1 light year from the Sun. It is thought to be the source of long-period comets that occasionally enter the inner solar system.
What does the solar system do?
A curious question.
Generally speaking, in and of itself, the Solar System doesn't DO anything except that it resides in a particular location in space. The Solar System is rather a place than a thing. The Solar System is a location where exists a group pf planets, (9 if you still think of Pluto as a planet, 8 if not) planetesimals, asteroids, comets, and our local star resides.
As a group of the above named items as well as all the other stuff, the Solar system has a gravitational effect in it's local, galactic neighborhood.
Perhaps you could refine your question, What is it you want to know about the Solar System.
Is there a new planet in your solar system?
No, there are no new planets in our solar system. They have all been here for a long time! Our solar system has eight planets, since Pluto was downgraded to a dwarf planet. There are some new dwarf planets: Eris, Ceres, and the newest MakeMake. There are about a dozen more candidates for dwarf planet status. Pluto, Eris, and MakeMake are also considered plutiods, which means they are beyond Neptune's orbit. See Related Links below for more information.
Which planet is known as the blue planet?
Earth is known as the blue planet because of its extensive oceans that give it a predominantly blue appearance when viewed from space. The reflection of sunlight off the oceans contributes to its blueness.
Rocky material is found everywhere in the Solar System because it is more resilient to the extreme conditions of space and is not easily vaporized. In the outer regions, such as the Kuiper Belt and Oort Cloud, where temperatures are colder, volatile materials like water, methane, and ammonia can exist in solid form, leading to their accumulation in larger quantities compared to the inner regions.
Venus is the warmest planet in our solar system, with an average surface temperature of about 465 degrees Celsius (869 degrees Fahrenheit). This extreme heat is due to its thick atmosphere, which traps heat from the sun and creates a runaway greenhouse effect.
How are the planets arranged in the solar system?
The planets are arranged in this order, from the Sun:
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.
At the centre of our Solar system, resides the Sun.
So, at the centre of The Solar System resides:
The Sun! - The Sun, also known as 'Sol' is at the centre of the Solar System. The Solar System we are in is called (literally): The Solar System
Then:
1. Mercury - This is the closest planet to the sun, is egg-shaped and orbits generally around 29,000,000 and 44,000,000 (Twenty Nine and Forty four Million) miles from the sun!
2. Venus - This is the second closest planet to the sun. It is riddled with mountains, lava and Volcanoes - But has a thick atmosphere stopping satellites and observatories from normally seeing its landscape. It orbits at around 67,000,000 million miles depending on the year.
3. Earth! This planet, the very planet we live on (Unless you're an Alien on the Internet!) is filled with Organic Life. Some scientists claim that Earth is the only planet in the universe that contains life, yet when you think there are countless Galaxies out there, and our own galaxy contains more than 200,000,000,000 (Two hundred BILLION) stars, you can't help but think, could there be life out there? Earth Orbits at 1AU(Astronomical Unit) from the sun, what is a total of 95.955.807.3 miles!
4. Mars - This planet is often visible to the naked eye. It is riddled with mountains and gigantic canyons formed billions of years ago (The actual plant is 4.6 BILLION years old! Then again, so is the rest of the Solar system.) Pictures from Probes and the Hubble Telescope have shown strange patterns on Mars - that, even after all these years, has scientists believing that water may have once flowed on Mars. (Like the sea on Earth, Mars may have once had water too!) It is around 155.000.000 (One hundred and fifty five) million miles from the sun.
5. Jupiter - This is the largest planet in the solar system. Under the constantly-raging storms, there is a liquid water and hydrogen ocean. This planet is approximately 483.000.000 (Four hundred and eighty three) Million Miles!
6. Saturn - Famous for its gigantic ring, this is the second largest planet in the solar system and is incredibly similar to Jupiter. It orbits at approximately 903.000.000 (Nine hundred and three) Million Miles!
7. Uranus - This planet in most aspects, is similar to the other Gas Giants
in the solar system - However, unlike the other plants in the solar system, Uranus spins on its side! Uranus orbits at approximately 1,708,111,170 (One billion seven hundred and eight million)miles and 1,866,859,850 (One billion eight hundred and sixty six million) miles from the sun!
8. Neptune - This is the smallest Gas Giant in the Solar system. Having only been visited once by the Voyager two, like the other Gas Giants, it is a planet with many storms. It orbits at approximately 2.800.000.000 (Two Billion Eight hundred) miles from the sun!
9. Pluto - This isn't actually a planet - But I figured it's still relevant to the Question! Pluto was known to be a planet before it was re-classified as a Dwarf Planet. Although furthest away from the sun, on occasion, because Pluto is within Neptunes Orbit, the dwarf planet can be closer to the sun than Neptune. It Orbits the sun between 2,756,915,000 (Two billion seven hundred and fifty six) and 4,583,189,130 (Four billion five hundred and eighty three) miles!
With the Sun at the centre, the following is the list of planets as one moves outwards. Figures in brackets are for the average radius of each planet's orbit measured from the Sun.
# Mercury (57,909,100 km) # Venus (108,208,930 km) # Earth (149,597,887.5 km)
# Mars (227 939 100 km) # Jupiter (778,547,200 km)
# Saturn (1,433,449,370 km)
# Uranus (2,876,679,082 km # Neptune (4,503,443,661 km) To help get a grasp on the distances it can help if we set Mercury's orbit as a standard and measure the others against it. In that way, Mercury has an orbit of 1 unit, and the others are as follows:
* Venus 1.9 units * Earth 2.6 units * Mars 3.9 units * Jupiter 13.4 units * Saturn 24.8 units * Uranus 49.7 units * Neptune 77.8 units
Pluto, the recently demoted 'dwarf planet' is at a distance of 5,906,376,272 km - or 102 units.
As can be seen there is an almost arithmetic progression in those units and the noticeable gap between Mars and Jupiter is where we find the asteroid belt - a wide area containing a vast amount of irregularly-shaped 'space debris' - dwarf planets, asteroids and rocks and dust.

Suns importance in solar system?
Clearly, we (Earth) can't live without the Sun. It gives us energy/ electricity and warmth. Plants need the Sun for photosynthesis, we need it as light during the day. The Sun plays a major role in our lives.
The importance of sun in our solar system is that if we don't have the sun then there will be no life on Earth since it is too cold for life to grow, and the Earth will be a frozen chunk of ice and moreover the Sun's gravity keeps Earth and the other planets in the solar system from flying off into deep space, and the Sun keeps the Earth warm, allowing living things to flourish. Without the heat from the Sun, our planet would be completely frozen and not allow life to exist.
What are the planets outside of our solar system called?
Planets outside of our solar system are called exoplanets. These are planets that orbit a star other than our Sun. Exoplanets have been discovered through various methods, including transit observations and radial velocity measurements.
How fast does the solar system travel around the galaxy?
The solar system travels around the center of the Milky Way galaxy at an average speed of about 514,000 miles per hour (828,000 km/h). This movement is due to the gravitational pull of the Milky Way's center, which keeps the solar system in orbit around it.
The six planets of the solar system?
The International Astronomical Union (IAU) recognises eight planets in our solar system (from closest to sun to furthest);
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.
What is the speed of the solar system?
Unless you specify relative to what, this is a meaningless question.
The sun dos NOT tvavelle
Which planet has the strongest winds in the solar system?
Neptune has the strongest winds in our solar system, with gusts reaching up to 1,300 miles per hour (2,100 kilometers per hour) on its surface. These high-speed winds are driven by the planet's fast rotation and its unique atmospheric dynamics.
Are stars part of your solar system?
No, stars are not part of our solar system. Our solar system consists of the Sun and all the objects that orbit it, such as planets, moons, asteroids, and comets. Stars are separate celestial bodies that exist outside of our solar system.
Which planet is not a terrestrial planet?
The planets that are not classified as terrestrial are Jupiter, Saturn, Uranus and Neptune. If you count Pluto as a planet then it would be a part of that list as well. Mercury, Venus, Earth and Mars are the terrestrial planets. Jupiter, Saturn, Uranus and Neptune are the gas giants. Pluto is a dwarf planet.
Which outer planet has the longest day?
Uranus has the longest day of any planet in the solar system, with a rotation period of about 17 hours and 14 minutes.
What is the closest solar system to earth?
Alpha Centauri is the closest star to our solar system, at about 4.2 Light Years.. It's not a solar system in the sense that ours is though - it's a triple star system composed of Alpha Centauri A (a little bigger than the Sun), Alpha Centauri B (a little smaller than the Sun) and Proxima Centauri (a red dwarf - very small star). Proxima Centauri is a long way away from A and B. Proxima may not actually be in orbit around A and B - it may leave the system in several million years. There may be planets in orbit around one of these stars, but we haven't detected them (yet).
The closest known solar system with planets is around Epsilon Eridani at 10.5 Light Years. Astronomers have actually photographed one planet around this star, and they believe there are probably at least 2 others.
Astronomers detect most planets by observing the wobble in the light from their host stars that occurs as planets orbit. It takes a long time to confim these observations, and it works best for large planets close to their host stars - so there are probably a lot of planets that we miss with this method.
Which planet is a stormy planet?
The second, third, sixth, and seventh planets orbiting the star Sol have sufficient atmospheres to have stormy weather. The sixth planet, Jupiter, might be known as the most stormy, as it currently has a centuries-old hurricane on it that is significantly larger than several of the other planets in the system.
What is the size of the solar system?
The size of the solar system depends on how one defines the outer limit, and scientists disagree on how it should be defined. By one definition the outer limit is two light years from the Sun. By another it is 95 times the distance from Earth to the Sun or about 15 ten thousandths (0.0015) of one light year.
What parts of earth receive the most solar heat?
The equator receives the most solar heat due to its direct exposure to the sun and minimal tilt of the Earth's axis. This region experiences consistent high temperatures throughout the year. Additionally, areas with clear skies, such as deserts, also receive high levels of solar heat.
What are the similarities of Mars Jupiter Saturn Uranus and Neptune?
They are all gas giant planets, with dense atmospheres with no clear separation of atmosphere and solid surface. They are all far from the Sun. They are all massive and have numerous moons.
