large clumps of ice, dust and frozen gases that travel around the Sun in long elliptical orbits, and are divided into 4 parts: Tail, Nucleus, Coma, and Head. These objects are the size of a mountain (without tail)
these rocky metallic objects that orbit the sun but are too small, and too numerious to be considered planets, and are found in the Asteroid belt, a region between Mars and Jupiter
Region between Mars and Jupiter
chunks of rock or dust from space, located in the Kuiper Belt, and the Oort Cloud
A bright streak of light that results when a meteoroid burns up in Earth's atmosphere (shooting star)
meteoroids that pass through the atmosphere & hit Earth's surface
the force of attraction between all masses in the universe
the tendency of an object to resist any change in its motion
What keeps the Earth in orbit with the sun, ane the moon in orbit with Earth?
Gravity, and Inertia
How does mass and distance effect the force of gravity?
Gravity increases as mass increases, and Decreases as distance increases.
Order of Planets
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, (Pluto)
Which planet is not considered a planet?
How does Inertia and Gravity combine to keep Earth in orbit?
Well, as gravity is pulling Earth towards the sun, Earth is pulling away from the sun with equal force by using Inertia
Differences between Meteoroids, Meteors, and Meteorites
Meteoroids= chunks of rock in space
Meteors= Meteoroids that burn up in the atmospere (Shooting Stars)
Meteorites= Meteoroids that make it through the atmosphere and hit the surface
