What else can I help you with?
Is the perimeter of a planet's orbit determined by how big or small it is or how hot the sun makes the planets?
NO, the orbit of any planet or moon is determined by the size of the two objects involved (example: the Earth and the Sun) and the distance between those two objects: the closer the objects are to each other and the bigger one of the objects is, the stronger the gravitational pull ( large objects have stronger forces on other smaller objects). The orbit of a planet has nothing to do with the Sun's heat.
Is earth orbit smaller than mars orbit?
Yes. Earth is closer to the Sun than Mars, so it will have a smaller orbit.
What smaller objects orbit a planets?
Moons.
Does smaller planet orbit bigger planet or does bigger planet orbit smaller planet?
Planets orbit stars, not other planets. A planet-like object that orbits a planet is a moon.
What is bigger than an asteroid?
lots of things are bigger than a astriod ,planets, somtimes a moon, and the biggest star in are solar system.
How does a planet's distance from the sun affect the length of its year?
the closer the smaller orbit (a year is one complete orbit) so the year is smaller
How do meteorites differ from asteroids?
Asteroids are objects smaller then planets that orbit the Sun. Meteorites are (usually) smaller objects that enter the atmosphere and reach the ground.
How do all planets orbit the sun?
Through gravitational pull. The largest object will have smaller objects orbit it (objects close in size will orbit each other, but no planet is close to the size of the sun)
Why do planets revolve around the sun and not the other way around?
The sun is much bigger than planets and has more mass, so it also has more gravitational pull. Objects in space with a greater gravitational pull can keep smaller objects in orbit.
Can a moon be bigger than a planet?
No, a moon cannot be bigger than a planet. Moons are natural satellites that orbit planets, and they are typically much smaller in size compared to the planets they orbit.
What is bigger meteor or asteroid?
Meteors are smaller fragments of asteroids or comets that enter Earth's atmosphere and burn up, causing a bright streak of light. Asteroids are larger rocky objects that orbit the sun. In general, asteroids are bigger than meteors.
Why is Eris not considered a planet?
Many smaller objects cross Eris' orbit, so it does not dominate its orbital path. An object must clear its orbit of other objects to be considered a planet.
