Gas giants

• The blocking of sunlight to the moon that occurs when Earth is directly between the sun and the moon.

• The name given to the four inner planets: Mercury, Venus, Earth, and Mars.

• The name given to the four outer planets: Jupiter, Saturn, Uranus, and Neptune

• Rocky objects revolving around the sun that are too small and numerous to be considered planets.

Two things needed to keep planets in orbit

• The spinning motion of a planet on its axis.

• gravity and inertia

• gravity and force

• The movement of an object around another object.

heliocentric

• The different apparent shapes of the moon as seen from Earth.

• The study of the moon, stars, and other objects in space.

Our position in the Milky Way

• in the center

• we aren't in the Milky Way

• under the Milky Way

• on an arm of the Milky Way

Comet's orbits are

• very long and narrow

• very wide and short

• no different than planets

• too dangerous to study

comet

• Rocky objects revolving around the sun that are too small and numerous to be considered planets.

• A streak of light in the sky produced by a burning meteoroid in Earth’s atmosphere.

• A chunk of rock or dust in space.

• A loose collection of ice, dust, and small rocky particles, typically with a long, narrow orbit of the sun.
