Answer:
8) A
A meteor is a streak of light in the sky caused by a meteoroid crashing through Earth's atmosphere. Meteoroids are lumps of rock or iron that orbit the sun.
9) C
Comets are frozen leftovers from the formation of the solar system composed of dust, rock and ices.
10) B
Comets are icy bodies in space that release gas or dust. They are often compared to dirty snowballs, though recent research has led some scientists to call them snowy dirtballs. Comets contain dust, ice, carbon dioxide, ammonia, methane and more.
11) A
Comets go around the Sun in a highly elliptical orbit.
12) maybe it's asteroid? (correct me if I'm wrong)
Isa lang kasi ang alam ko which is the Hercules-Corona Borealis Great Wall
The largest known 'object' in the Universe is the Hercules-Corona Borealis Great Wall. This is a 'galactic filament', a vast cluster of galaxies bound together by gravity, and it's estimated to be about 10 billion light-years across!
13) I think it's silicon (correct me if I'm wrong)
14) B
Asteroids most appear rocky, likely contain iron/nickel
15) A
The dust tail forms from those dust particles and is blown back by solar radiation pressure to form a long curving tail that is typically white or yellow in colour.
16) A
Tails behind the comet, pointing away from the Sun as the comet approaches it, and
towards the Sun as the comet moves out of the inner Solar
