Astronomy and Space Quiz

Heliocentric

• Gas and dust at the center grow dense and hot.

• large clumps of ice, dust and frozen gases that travel around the Sun in long elliptical orbits

• a small body moving in the solar system that would become a meteor if it entered the earth's atmosphere.

• A model of the solar system in which Earth and the other planets revolve around the sun

Solar System Formation

• large clumps of ice, dust and frozen gases that travel around the Sun in long elliptical orbits

• the path that a body follows as it travels around another body in space

• -Fusion reactions begin; the sun is born. It begins to spin and flatten into disc. Particles begin to clump together forming planets.

• Gas and dust at the center grow dense and hot.

-Fusion reactions begin; the sun is born. It begins to spin and flatten into disc. Particles begin to clump together forming planets.

• Outer part of spiral arm

• The movement of an object around another object

• the path that a body follows as it travels around another body in space

• -Fusion reactions begin; the sun is born. It begins to spin and flatten into disc. Particles begin to clump together forming planets.

light year

• The distance that light travels in one year

• the path that a body follows as it travels around another body in space

• -Fusion reactions begin; the sun is born. It begins to spin and flatten into disc. Particles begin to clump together forming planets.

• Large cold planets with ring systems, many moons and lack solid surfaces, Jupiter, Saturn, Uranus, Neptune

gas planets

• objects that orbit the earth that are not man made - the moon is an example

• A device built to observe distant objects by making them appear closer

• Gas and dust at the center grow dense and hot.

• Large cold planets with ring systems, many moons and lack solid surfaces, Jupiter, Saturn, Uranus, Neptune

The terrestrial planets are

• The distance that light travels in one year

• the galaxy containing the solar system

• Mercury, Venus, Earth and Moon, Mars.

• A model of the solar system in which Earth and the other planets revolve around the sun

Milky Way Galaxy

• Outer part of spiral arm

• An object that revolves around another object in space

• Solar system evolved from an enormous rotating cloud called the solar nebula

• the galaxy containing the solar system

spiral galaxy

• a galaxy with a bulge in the middle and arms that spiral outward in a pinwheel pattern Ex: Milky Way Galaxy

• a large spiral galaxy about 2 million light years away

• A device built to observe distant objects by making them appear closer

• a small body moving in the solar system that would become a meteor if it entered the earth's atmosphere.

satellite
