Models of the Universe & Solar System

Astronomy

• The study of celestial objects, space, and the universe as a whole.

• The study of weather patterns and atmospheric phenomena.

• The study of ancient civilizations and their cultures.

• The study of the Earth's physical structure and substance.

Milky Way Galaxy

• The galaxy in which Earth and the Sun are located.

• A spiral galaxy located in the Andromeda constellation.

• A galaxy that is home to the nearest star system, Alpha Centauri.

• A galaxy that contains only dark matter and no stars.

Universe

• All of space and the matter space contains.

• A vast collection of stars and planets only.

• A term used to describe the Earth and its atmosphere.

Heliocentric Model

• A model showing the Earth as the center of the Universe with objects revolving around it.

• A model showing the Sun as a fixed point in the center of the Universe, with objects revolving around it.

• A model that describes the motion of the stars in the night sky.

• A type of planet.

• A small cluster of asteroids.

• A region of empty space.

Orbit

• A straight line path followed by a satellite as it moves away from the object.

• A curved path followed by a satellite as it revolves around the object.

• A circular path that is always stationary in space.

• A random path taken by a satellite without any specific direction.

Astronomer

• A scientist who studies objects in space, such as black holes, galaxies, moons, planets, stars, etc.

• A person who designs telescopes and other astronomical instruments.

• An individual who studies the weather and atmospheric conditions.

• A researcher focused on the history of space exploration.

Geocentric Model

• A model showing Earth located at the center of the universe.

• A model where the Sun is at the center of the universe.

• A model that describes the motion of planets around the Earth.

• A model that suggests the Earth is flat.

Solar System

• A collection of stars in a galaxy.

• A star and the group of planets and other celestial bodies that are held by its gravitational attraction and revolve around it.

• A cluster of galaxies in the universe.

• A group of moons orbiting a planet.

Big Bang Theory

• A theory that the universe is static and unchanging.

• A theory that says the universe began as a small point that expanded rapidly about 13.7 billion years ago.

• A theory that suggests the universe will eventually collapse back into a singularity.

• A theory that proposes the universe is infinite and has no beginning.
