How do astronomers think craters were created on the moon and planets?
Impact by asteroids.
What are small planets with orbits between mars and Jupiter?
Asteroids
How do scientists think about rainbows?
Scientists can learn a large amount of information about light from rainbows.
What scientists travel in spacecrafts?
i think astronauts
Why does Mars have two moons?
There's no special reason. That's just how things have turned out. Some scientists think they may just be "captured" asteroids, but this is not certain. Also, the orbit of Phobos, the moon closest to Mars, is unstable and Phobos should break up and crash into Mars in 50 million years or so.
Where do scientists think asteroids come from?
They are concentrated between the Mars and Jupiter.
Why do you think scientist have not named all of the asteroids in the asteroid belt?
Scientists may not have named all of the asteroids in the asteroid belt because there are so many that they are hard to keep track of.
Why do scientists think asteroids are between mars and Jupiter?
Because they have been observed and space probes have navigated through them.
When do scientists think the asteroids orginated?
At the same time that the Earth (and the other planets) formed : 4.5 billion years ago.
How do scientists track Asteroids in space?
with computers and devices
How old do scientists think asteroids are?
About the same age as the time of formation of the solar system: 4.6 billion years to 4.7 billion years.
How many asteroids does Kuiper belt have?
It doesn't seem that scientists are anywhere near to knowing the total number of asteroids in the Kuiper belt.
What tools do scientists use to study asteroids and comets?
Absolutely nothing.
Why does asteroids lie between mars and Jupiter?
Scientists think that the asteroid belt is a group of planetesimals (solid objects) that are caught between the gravity of Jupiter and the Sun.
How many asteroids in the kuiper belt?
there are so many, scientists don't know.
What are 2 ideas regarding the origin of the asteroids in the asteroid belt?
A) Some scientists suppose that the asteroids represent pieces of a planet that once existed but was torn apart a long time ago. B) Other scientists believe that the asteroids are material that never came together to form a planet in the first place.
Where would you most likely find?
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.
