Our nearest star AFTER the SUN. Located over 4 light years away.
What is Alpha Centauri?
200
A system of millions or billions of stars, together with gas and dust, held together by gravitational attraction.
What is a Galaxy?
200
On this planet, it takes 243 Earth Days to equal one day here due to it's slow rotation. Very similar to Earth in size and the fact that it has a crust, mantle, and central core. Second brightest object in the night sky.
What is Venus?
200
Tipped on its side, this planet has an icy mantle, atmosphere made of water, ammonia, and methane so it appears blue. This is the coldest planet with 27 moons and 13 rings.
What is Uranus?
300
The nearest large Galaxy to ours (the Milky Way). Located over 2,900,000 light years away.
What is the Andromeda Galaxy?
300
Is a spiral-shaped disc with many arms with over 200 billion stars, 120,000 light years across, and contains a black hole at the center... also home to Earth.
What is the Milky Way Galaxy
300
This planet is closest to the sun and is the smallest planet. A year is 88 days long and it is the most cratered planet.
What is Mercury?
300
Furthest planet from the sun, it takes 164 Earth years to orbit the sun. This planet appears blue and is the smallest of the outer planets but still much larger than Earth.
What is Neptune?
400
Spacecraft heading out of our solar system at 62,000 kilometers per hour but will take 77,000 years to reach the nearest star after the Sun and over a billion years to cross the Milky Way at that speed.
What is Voyager I?
400
The star that Earth orbits. Uses nuclear fusion in its core to generate heat and light and composed primarily of hydrogen and helium gas.
What is the Sun?
400
Closest planet to the Sun and also the smallest planet, this planet has the most craters of any planet, is second hottest and has been visited twice by Earth spacecraft.
What is Mars?
400
This planet is 2 and a 1/2 more massive than all other planets. It has 67 known moons and 4 rings. This planet has the shortest day at almost 10 yours but takes 11 years to orbit the sun (have a year).
What is Jupiter?
500
The measure of the distance from the Earth to the Sun... approximately 150 million kilometers (93 million miles)
What is an Astronomical Unit?
500
Diameter of this object is 109 times greater than that of Earth. Over 1 million Earths would fit inside the Sun's volume.
What is the Sun?
500
The other name for the inner planets due to their "rocky" surfaces.
What are TERRESTRIAL Planets?
500
The large planets that contain more than 10 times the mass of Earth and are composed mostly of gas.
What are the Gas Giants?
500
A small rocky or metallic chunk of material that travels through space. These fragments may be leftover comet debris, or were ejected in collisions between other solar system bodies such as the Moon or Mars. They heat up as they approach the sun and form tails, leading some to call them shooting stars.
