AIt does not possess enough mass to assume a nearly round shape.

BIt orbits a larger planet rather than circling the Sun directly.

CIt has not cleared the neighborhood of debris surrounding its orbit.

DIt is composed primarily of ice and dust rather than rocky or metallic minerals.

Question No. 2

Consider the following statements:
1.The Asteroid Belt is a region of rocky and metallic remnants situated specifically between the orbits of Mars and Jupiter.
2.The Kuiper Belt is a disk of icy bodies and dwarf planets located just beyond the orbit of Neptune.

A1 only

B2 only

CBoth 1 and 2

DNeither 1 nor 2

Question No. 3

Consider the following statements:
1.A Ploonet is a celestial body that was originally a moon but escaped its planet’s gravity to orbit its host star directly.
2.The Goldilocks Zone refers to the region in a galaxy where the concentration of heavy metals is high enough to form terrestrial planets.

DThey are man-made debris fields found exclusively in Low Earth Orbit.

Question No. 5

Consider the following statements regarding Space Debris:
1.The majority of space junk is concentrated in High Earth Orbit (HEO) to avoid atmospheric drag.
