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

Spherical, orbits the Sun, with a larger mass than nearby objects.

A streak of light produced when a small piece of rock or ice, known as a meteoroid, burns up as it enters Earths atmosphere.

A cold mixture of dust and ice that develops a long trail of light as it approaches the sun.

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

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.

The movement of one object around another.

Path planets follow when they revolve around the sun.

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 which causes equal day and night.

The force that attracts all objects toward each other.

Law of universal gravitation

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

Force that keeps planet in motion.

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 and new moons.

Lower high tides during the first and third quarter moons.
