• meteor
• asteroid
• comet

Comet

• any natural satellite that orbits a planet, including -and most often- captured asteroids
• a ball of frozen dust and rock that has very long elliptical orbit and takes hundreds of years to orbit the sun
• a measure of how much matter is in an object
• a rocky body smaller than an asteroid. when they enter our atmosphere, they burn up from air friction and make shooting stars

Redshift

• objects moving away from us very quickly will have longer slower wavelengths that are more stretched out and appear red (like the slow light at the end of a sunset)
• objects moving towards us quickly will have shorter faster wavelengths that appear more blue
• An object that orbits the sun but is not completely spherical or does not have enough gravity to clear the rocks and debris out of its own orbit

Tags

NGSS.HS-PS4-3

Satellite

• any small celestial bodies composed of rock and metal that orbit the Sun
• an object that orbits a star, is large enough to have become rounded by its own gravity, and has cleared the area of its orbit.
• any object that orbits another object in space, man-made, such as those used for GPS, or natural, such as moons
• any natural satellite that orbits a planet, including -and most often- captured asteroids
