Describe
THE PHYSICAL PROPERTIES, LOCATIONS, AND MOVEMENTS OF THE SUN, PLANETS, MOONS, METEORS, ASTEROIDS, COMETS, KUIPER BELT, AND OORT CLOUD
Including, but not limited to:
Sun
Physical properties
Composed of hydrogen and helium gas
Hottest object in our solar system
Produces light
Largest and most massive object in our solar system
Location
In the center of the solar system
Movement
Rotates on its axes
Planets
Terrestrial planets (Mercury, Venus, Earth, and Mars)
Physical properties
Composed of rock
Thin atmospheres of gas
Smaller, less massive planets
Location
Closest planets to the Sun
Movement
Orbit the Sun
Rotate on their axes
Jovian planets (Jupiter, Saturn, Uranus, and Neptune)
Physical Properties
Composed of rock and ice
Thick atmospheres of gas
Larger, more massive planets
Location
Farthest planets from the Sun
Movement
Orbit the Sun
Rotate on their axes
Moons
Physical properties
Smaller than the planets they orbit
Composed of rock
Very thin or no atmosphere
Location
Orbiting most planets
More moons orbit Jovian planets
Movement
Orbit a planet
Rotate on an axis
Meteors
Physical properties
Small dust particles / debris from comets
Burn when entering Earth’s atmosphere causing light
Location
Left in the path of comets that passed through the area before
Movement
Orbit the Sun
Fall towards Earth when entering the atmosphere
Asteroids
Physical properties
Composed of rock
Smaller than terrestrial planets
Location
Between the orbits of Mars and Jupiter
Movement
Orbit the Sun
Comets
Physical properties
Composed of rock and ice
Form large tails of gas and dust as they melt when they are near the Sun
Location
Originate from the Kuiper belt or Oort cloud
Movement
Large, elliptical orbits around the Sun
Kuiper belt
Physical properties
Composed of small rock and ice objects that could become short period comets
Thin, disk-shaped group of objects
Location
Beyond the orbit of Neptune, between 35-50 times further from the Sun than Earth
Movement
Orbit the Sun
Oort cloud
Physical properties
Composed of small rock and ice objects that could become long period comets
Sphere shaped group of objects
Location
Furthest objects from the Sun still considered to be in the solar system
Between 2,000 and 100,000 times further from the Sun than Earth
Movement
Orbit the Sun
