Traveling from Earth you would encounter the asteroid belt before you reach this planet

Jupiter
Saturn
Uranus
Neptune

Jupiter

That's right, you reach the asteroid belt before you reach all 4 of these planets.
Now, all you have to do is find out which planet is closest to the sun of these 4 and you know which one you reach first (probably take about 2 seconds).

All four are correct.

The asteroid belt is between the orbits of Mars and Jupiter. Saturn, Uranus, and Neptune all have orbits farther from the Sun than Jupiter.

The correct answer is Jupiter. It is obvious the question means "which is the first planet you would reach after the asteroid belt."

All of them, actually.... The asteroid belt is mostly between Mars and Jupiter - and all these planets listed lie beyond. (Jupiter would be first, however.)

Jupiter

You can avoid the Asteroid belt by either going "over" or "under" it in three dimensions

You would encounter the asteroid belt before you reached Jupiter, Saturn, Uranus, or Neptune.

The asteroid belt is between the orbits of Jupiter and Mars so therefore yes.

There are hundreds of millions of asteroid belts even more but in our solar system its Jupiter
