the main way scientist find new asteroids is through imaging them. They bring telescopes' large reflectors to a location in an area where they think the planet will be. They take an image, and then, from a couple minutes to a couple weeks later, they take another image of the same spot. anything that moves from each slide, they will check to see if it is an already existing and known object, or a man-made object, or fake. If the object is real, they will take several follow-up pictures to learn more about the asteroid's speed/trajectory/distance from the sun. the asteroid has been assigned a classification number once it has been proven to exist. once the orbital/physical mechanics of the asteroid have been discovered, the asteroid will be named. The namer may name the asteroid (only if it is a minor body) whatever they want, from xyyxxxxyyyzzz to blue purple-greenscreen. If the asteroid is large, it will be named according to what part of the solar system it resides in.
Scientists assume that the meteors, asteroids, and comets were created at the same time as the solar system. Those have rocks that contain radioactive materials. The radioactive materials became a part of those rocks when they were created. None were ever added. It is possible to find the rate at which radioactive materials decay into other elements. Scientists can take the radioactive material in a rock and measure it and compare the amount of its decay results to their tables in a book. That tells them the Solar System is something between 4 and 5 billion years old.
small pieces of debris that are from other comets, asteroid's, etc colliding togetherMeteoroids are formed by; Scientists look at what they know--the form and composition of meteorites as the see it in the laboratory and the form and composition of the universe as they see it through their telescopes. They then make a guess--pose a hypothesis--as to how meteorites formed. They test the hypothesis by trying to prove it false. Following are the current theories of how meteorites formed:
Yes, scientists have discovered many new planets outside the solar system, known as exoplanets. Statistical models indicate there are hundreds of billions of such planets within the Milky Way.
The largest collection of asteroids is found orbiting the Sun between orbits of Mars and Jupiter, This area is sometimes called the "asteroid belt". Think about it this way: the asteroid belt is a big highway in a circle around the Sun. The asteroids are like cars on the highway, except that they are thousands of miles apart on the average. Even so, sometimes the asteroid cars run into one another. When this happens, the asteroids may break up into smaller asteroids. Scientists think that most asteroids are the result of collisions between larger rocky space bodies. Asteroids can be a few feet to several hundred miles wide. The belt probably contains at least 40,000 asteroids that are more than 0.5 miles across. If an asteroid is disturbed by the gravitational pull of a planet, or is involved in a collision, it can be thrown out of the belt and go into orbit as a moon. Some of Jupiter's many small moons were likely once asteroids.
Planets like earth and mars. Asteroids, dust, debris from spacecraft, moons, and the sun.

in the solar system
Astronauts go to different planets etc and collect specimens and other things so that scientists can research and find out more about our solar system.
A star and more specifically, in our solar system, the Sun.
To find whats in it. We are exploring the solar system to gain knowledge about it's contents. Many scientists are intrigued by the solar system and it's many planets and stars, therefore want to learn more about them.
We don't really know how much water there is in the solar system. Europa, one of Jupiter's 63 moons, might have a tremendous amount of water. Scientists continue to find water; even on our own moon.
so they can find out about the early solar system and how planets were formed
Little craters because Venus is the hottest planet in our solar system, so any comets or asteroids would burn up because of the heat or in the thick atmosphere.
