Large and small rock like objects that orbit mainly in a belt between Mars and Jupiter.
The scientific study of matter in outer space
An imaginary line that runs from the north pole to the south pole. Earth is tilted on its axis 23.5 degrees.
objects made up of gas, ice and dust, as they approach the sun it melts forming a “tail”.
The blocking out of one object in space by another (sun, moon).
Stored energy from the sun found in fossils of ancient plants and animals (example coal and oil).
Massive amount of millions of stars all orbiting a common center
The amount of matter in something.
A small solid body entering a planets atmosphere.
Natural satellite of Earth visible only by reflecting sunlight.
The path of one object as it goes around another object.
The process of plants making food by using energy from the sun.
A body that orbits the sun, has its own gravity that has made it round, and has cleared smaller objects out of its part of space.
The star that is the center of our solar system. Provides energy in the form of heat and light.
Earth’s movement around the sun. It takes 365 days, or 12 months, or 52 weeks.
A turning motion on an axis. Earth’s rotation gives us day and night. It takes 24 hours for earth to rotate once.
Natural division of the year in terms of weather conditions caused by the Earth going around the sun on its axis.
The rising and falling of Earth’s water because of the gravity of the moon and sun.
The moon as it appears at a particular time in its cycle. Takes 29.5 days to complete one lunar cycle around the Earth
Natural force of attraction between all objects in the universe. The larger the mass the larger the attraction
Third planet from the sun. Only known planet to support life with water and a breathable atmosphere.
The rough image cast by an object by blocking light.
A system of planets and other bodies orbiting a star.
Tool used to see object close up from far away.
