that Saturn is farther away from the Sun than Earth is
10) Which of the following best describes the dust, gas, and celestial bodies of the Milky Way Galaxy?
A
The farther away they are from the center of the galaxy, the more they are pulled by gravity.
B
They orbit around the center of the galaxy because of gravity.
C
The faster they move, the less gravity they experience.
D

A
Only single atoms existed in the Universe, and they were squeezed together by magnetic fields.
B
Only protons and electrons existed in the Universe, and they were pulled together by gravity.
C
All mass in the Universe was in the form of gases, and gases take up minimal space.
D
