Question 1

The asteroid Ida was found most importantly and strangely to have _________.&#10;A) a surface&#10;B) craters&#10;C) a moon&#10;D) a volcano

Accepted Answer

Ida was found to have a moon, named Dactyl, making it one of the first asteroids discovered to have a natural satellite.

Question 2

This asteroid has been classified as a dwarf planet:&#10;A) Ceres&#10;B) Vesta&#10;C) Pallas&#10;D) 1 asteroid

Accepted Answer

Ceres is the only object in the list that has been classified as a dwarf planet by the International Astronomical Union (IAU). It is the largest object in the asteroid belt between Mars and Jupiter.

Question 3

These are small rocky bodies primarily found near Mars and Jupiter:&#10;A) comets&#10;B) asteroids&#10;C) KBOs&#10;D) TNOs

Accepted Answer

Asteroids are small rocky bodies that are primarily found in the asteroid belt, a region of space located between the orbits of Mars and Jupiter. This area is filled with numerous objects that range in size from tiny pebbles to objects hundreds of kilometers in diameter.

Question 4

The Trojan asteroids travel along the orbit of&#10;A) Jupiter&#10;B) Mars&#10;C) Earth&#10;D) Saturn

Accepted Answer

The Trojan asteroids are a group of asteroids that share the orbit of Jupiter, clustered around the two Lagrangian points of stability, L4 and L5, which precede and follow Jupiter in its path around the Sun.

Question 5

This was the mathematical pattern discovered for the known planets in the 1700s:_________.

Accepted Answer

The answer of This was the mathematical pattern discovered for...

Question 6

More empty regions in the asteroid belt regions are called the _________.

Accepted Answer

The answer of More empty regions in the asteroid belt...

Question 7

Irregular light patterns in asteroid observations suggest that most rotate in 3 to 10 hours.

Accepted Answer

Asteroid observations often show irregular light patterns due to their uneven shapes and reflective properties. These patterns suggest that most asteroids complete a rotation in a period ranging from 3 to 10 hours, as the observed light changes are caused by the asteroid's rotation bringing different surfaces into view.

Question 8

Trojan asteroids cross the Earth's orbit.

Accepted Answer

Trojan asteroids are located in the same orbit as a planet but remain in stable positions either 60 degrees ahead of or behind the planet, primarily associated with Jupiter, not crossing the Earth's orbit.
