Question

asteroids orbit stars along nearly circular or oval - shaped paths. most asteroids in the solar system orbit the sun in the asteroid belt, a region of space between the orbits of mars and jupiter. however, if disturbed by gravity, some asteroids can travel toward the sun into the inner solar system.
asteroids are much smaller than planets, ranging in size from 1 meter to 530 kilometers in diameter. they are usually irregular in shape, although some of the largest asteroids are rounded. they are typically made of rock or metal, and many have craters on their surface.
select the true statements about asteroids in the solar system.
a diameter of 280 kilometers is within the normal range for an asteroid.
most asteroids are irregular in shape.
many asteroids orbit the planets mars and jupiter.
asteroids usually have smooth, icy surfaces.

Explanation:

1. For "A diameter of 280 kilometers is within the normal range for an asteroid": The text says asteroids range from 1 meter to 530 kilometers in diameter, so 280 km is within this range.
2. For "Most asteroids are irregular in shape": The text states "They are usually irregular in shape, although some of the largest asteroids are rounded", so this is true.
3. For "Many asteroids orbit the planets Mars and Jupiter": The text says most asteroids orbit the Sun in the asteroid belt between Mars and Jupiter's orbits, not the planets themselves, so this is false.
4. For "Asteroids usually have smooth, icy surfaces": The text says they are typically made of rock or metal and many have craters, so this is false.

So the true statements are the first two.

Answer:

A. A diameter of 280 kilometers is within the normal range for an asteroid, B. Most asteroids are irregular in shape
