What is the sun made out of NASA?
Space & NavigationStructure. The Sun is a huge ball of hydrogen and helium held together by its own gravity. What is the Sun in space made of? The sun is a big ball of gas and plasma, but what is the sun made of exactly? Most of the gas — around 92% — is hydrogen, according to
How do you measure the diameter of a pole?
Space & NavigationStep 1 – Measure the circumference of the post (distance around the post). Step 2 – Take that measurement and divide it by pi (3.14) to determine the post diameter. What is the diameter at the pole? Equatorial vs Polar Diameter: Because of this, the diameter of the Earth at the equator is about 43
What holds the sun together?
Space & NavigationStructure. The Sun is a huge ball of hydrogen and helium held together by its own gravity. How does the Sun stay in one place? The Sun spins or rotates on its axis in the same direction as Earth (counterclockwise, when looking down from the north pole). Because it is a gas, it does not
What does Blue shifting mean?
Space & NavigationWhat does Blue shifting tell us? When an object is moving away from us, the light from the object is known as redshift, and when an object is moving towards us, the light from the object is known as blueshift. Astronomers use redshift and blueshift to deduce how far an object is away from Earth,
Can you have a slant and horizontal asymptote?
Space & NavigationA graph can have both a vertical and a slant asymptote, but it CANNOT have both a horizontal and slant asymptote. You draw a slant asymptote on the graph by putting a dashed horizontal (left and right) line going through y = mx + b. Can horizontal Asymptotes be slanted? A slant asymptote, just like
What are pieces of rock that strike the surface of a moon or planet?
Space & NavigationThe pieces that do strike Earth’s surface are called meteorites. Both meteors and meteorites can become natural hazards to the communities they impact. Very large meteors called bolides may explode in the atmosphere with the force of 500 kilotons of TNT. What do you call a rock from space that strikes Earth’s surface? This glowing
