Stars
The process that occurs in the center of a star that creates energy and causes the star to shine.
What is Nuclear Fusion
The outermost layer of the Sun
What is Corona
This is a HUGE system of gas, dust, and stars. Our solar system is found at one of the far edges of it.
What is the Milky Way Galaxy
This describes a complete circular trip around a fixed point by a planet or moon.
What is a Revolution?
This describes how earth's axis angle changes direction over time.
What is precession?
A large cloud of dust and gases where stars are "born"
What is a nebula
The primary composition of gases of our Sun
What is Hydrogen and Helium
The category of planets that are smaller in size, more dense, and rocky
What are Terrestrial planets
When the moon moves between the Sun and the Earth
What is a Solar Eclipse
This is Earth's axis tilt angle, which is a direct cause of Earth's seasonality.
What is 23.5 degrees?
This system describes a solar system with the Sun at the center of an elliptical path.
What is heliocentric model?
The size of our star/Sun
Low mass or Medium
The category of planets that all have rings, moons, and are gaseous (made primarily of hydrogen & helium)
What are Jovian planets
The shape of the planets orbits around the sun
What is elliptical
This describes the process of Earth's axis angle changing (within a degree up or down), over the course of 18.6 years.
What is nutation?
This is the innermost part of the star where it's energy is generated
What is the Core
These are dark areas on the sun's surface (photosphere) that are cooler than the surrounding area
What are sunspots
Located between Mars and Jupiter, this filled with millions of space rocks floating around the solar system.
What is Asteroid Belt
An object spinning around its own axis. The speed of this describes the "day-length" of a planet.
What is Rotation
This astronomer supported the Heliocentric model proposed by Copernicus. As a response (and due to his popularity), he was given a sentence of life-imprisonment by the Catholic Church.
Who is Galileo Galilei?
How do/did heavy elements (like gold and mercury) form in the universe
What is Supernova (star explodes)
This is the end stage of our stars life
What is White dwarf star (will eventually cool to a black dwarf)
The reason we always see the same side of the moon
What is being Phase locked or moon's revolution equals its rotation!!!! This is crazy!
The astronomer that believed our Solar System was Heliocentric (Sun Centered)
Who is Copernicus
Describe the differences between neap and spring tides (draw on board)!
See board for full explanation!
