A giant ball of superheated gas, or plasma, composed of hydrogen and helium.

Spherical, orbits the sun, with a larger mass then nearby objects.

A streak of light produced by a small piece of rock or ice.

A cold mixture of dust and ice that develops a long trail of light.

A pattern or group of stars that people imagine represents a figure, animal, or object.

An oval shape of the plants’ orbits

An imaginary line that passes from the north Pole to the South Pole

The spinning of earth on its axis

Is the movement of one object around another. (1 revolution takes 1 year)

Earths path around the sun is an ellipse

Earth is most tilted toward or away from the sun which causes the longest or shortest daylight of the year.

Earth is not tilted toward the sun with causes equal day and night.

Force that attracts all objects toward each other

Law of universal gravitation

Every object attracts every other and its force depends on mass and distance

Different shape of the moon you see

When the moon passes directly between the Earth and Sun during a new moon

Occurs during a full moon when Earth is directly between the moon and sun.

Darkest part of a shadow where light is completely blocked

Area of a shadow where light is partially blocked

Daily rise and fall of ocean water

Higher high tides during full moon and new moons.

Lower high tides during the first and third quarter moon.

Dark, smooth, lava covered area on the moon

Higher lighter areas on the moon covered with craters

Largest object in out solar system
