Asteroids are all different shapes and sizes.
No. All planets are spherical.
No, they are the size of uranus ;)
Dwarf Planets actually orbit the Sun on an orbital path. Unlike Asteroids they have a moon as well. Asteroids usually stay in a belt like the one between Mars and Jupiter. Yet not all Asteroids are in the belt some of them are close to Earth. This type of Asteroid is called a NEO. (Near Earth Object). Asteroids don't orbit the Sun like planets do in their orbital paths. Asteroids tend to go in anyway they want. Just a simple push from another object if not already heading for Earth can push an Asteroid on a different course which could also be a danger to Earth itself. Asteroids also contain life supporting elements and materials that we could mine out of them which NASA (National Aeronautics and Space Administration), other government's, and even privet company's are trying to find a way to do so. If we can mine Asteroids we could just be able to get to Mars very soon.
The planets mass creates gravity which pulls it into a spherical shape. This is the difference between planets and other heavenly bodies such as moons and asteroids. To be defined as a planet, a body must have enough gravity to pull itself into a spherical shape and it's gravity must be sufficient to clear its area of other debris.
Asteroids have many shapes, depending on their mass or composition. The largest are spherical, but others and elongated spheres, potato shaped and even resemble peanuts. Mostly, they are irregular shaped rocks.
because they were created like that
There are many ways the planets are different. One way is that they all have different gravity levels, they are all different shapes and sizes. Lastly that they are different temperature, and different material.
asteroids come in shapes and sizes
yes
Scientist classifies these objects based on their sizes, shapes, compositions, and orbits. The major categories include dwarf planets, comets, asteroids, and meteoroids.
All the planets are spheres.
All orbits are ellipses.
