object to continue in a
straight line or a
stationary object to
remain in place

that revolves around Earth
at the same rate that Earth
rotates
15. any natural or artificial
object that revolves
around an object in space

sun’s atmosphere; the
part of the sun that we see
17. a description of the
solar system that the
Greeks believed in which
all of the planets revolve
around Earth
18. rotating in the opposite
direction from most other
planets; Venus rotates in
this way
19. a large planetary
system that consists of a
combination of many
smaller planetary systems
and object
20. electrically charged
particles that stream from
the sun’s corona and are
usually blocked by the
Earth’s atmosphere and
magnetic field
21. the combining of 2
atomic nuclei to produce a
single larger nucleus
22. the forces that attracts
all objects toward one
another
23. the first four outer
planets
24. streaks of light we see
in the sky caused by
meteoroids’ friction with
the atmosphere
25. movement of the planet
around the sun
26. the spinning motion of
a planet on its axis
27. meteoroids that pass
through the atmosphere &
hit Earth’s surface
28. areas of gas on the sun
that are cooler than the
gases around them and
the number varies every
10-11 years
29. the region of the solar
system between Mars &
Jupiter where many
asteroids are found
30.___ proposed that the
planets’ orbits was
elliptical.
31. The ___ are generally
larger & further from the
sun.
32. The atmospheres of the gas giants
cannot escape into space because
a. the gases are too heavy.
b. the gases solidify at higher
elevations.
c. the planets have very strong gravity.
d. although the are big, the planets
