What is a star?
100
This is a measure of the total amount of energy a star gives off each second.
What is luminosity?
100
This is a group of stars in the sky that form a picture to which scientists have given names based on Greek mythological characters.
What is a constellation?
200
A collection of stars, dust, and gas bound together by gravity.
What is a galaxy?
200
The nuclear fusion that takes place in a star begins with this element.
What is hydrogen?
200
The sun is this size compared to other stars in the solar system.
What is a medium-sized star?
200
A star that is one of the highest temperatures for a star will be this color.
What is blue?
200
A spherical body that orbits the sun.
What is a planet?
300
This is space and all of the matter and energy in it.
What is the Universe?
300
A high mass star will fuse and grow larger forming a supergiant. It will eventually explode throwing its outer layers into space. This is the name of the explosion.
What is a supernova?
300
The measure of a star's brightness as seen from Earth.
What is apparent magnitude?
300
Two stars clustered together form this.
What is a binary star system?
300
A dim star would be located here on the HR diagram.
What is the bottom of the diagram?
400
This planet is large, gaseous, and located far from the sun.
What is an outer planet?
400
A low mass star that is no longer undergoing nuclear fusion will expand to form a giant star and then this.
What is a white dwarf?
400
This is used to plot the temperature and brightness of stars.
What is the HR diagram?
400
Polaris has an apparent magnitude of -1.3 and Cosmo has a magnitude of 2.4. This star has a lower apparent magnitude.
What is Cosmo?
400
The region of the HR diagram where stars spend most of their lives.
What is the Main Sequence?
500
This explains why humans have not been able to travel to other celestial bodies.
What is how light years have affected the ability to travel?
500
At the end of the life cycle of a high mass star, it expands to form a supergiant. It then may become this.
What is a neutron star or a black hole?
500
The Earth is a smaller planet in our solar system. This type of star is about the size of Earth.
What is a white dwarf?
500
The absolute magnitude of Sirius is the same as Centoria. However, because Centoria is farther away from the Earth, it appears to be dimmer than Sirius.
What is why Centoria has a lower apparent magnitude?
500
A low mass star such as the sun, at the end of its life cycle will become a giant and move will be here on the HR diagram.
