Constellations
The number of constellations recognized by the International Astronomy Union.
What is 88?
The theory that places Earth as the center of the universe.
What is geocentric? (or earth-centered)
These stars are one hundred times more luminous than any other star.
What are super giants?
The first four planets in our solar system.
What are the terrestrial planets?
This term describes an object moving closer, shortening its wavelength.
What is Blueshift?
This term describes twelve constellations along the ecliptic.
What is the Zodiac?
This theory explains that the sun is at the center of the universe.
What is heliocentric? (or sun-centered)
These stars change brightness over a period of time.
What are variable stars?
Although Pluto is no longer a planet, it is considered to be this type of planet.
What is a dwarf planet?
The end state of a medium mass star.
What is a white dwarf?
This type of constellation is caused by the rotation of Earth, and appears to be moving counter-clockwise from Polaris.
What is a circumpolar constellation?
This theory explains that interstellar dust grains help cool the cloud, and operate as nuclei.
What is the Condensation Theory?
It is the death of a high mass star and has two types, both relatively common.
What is a supernova?
*DAILY DOUBLE* (Minimum Wager is 100 points) Asteroids, comets, and meteors are part of this astronomical term.
What is interplanetary debris?
This law limited the use and the production of chlorofluorocarbons (CFC's).
What is the Montreal Protocol?
Vega, Altair, and Deneb are the first three bright stars that make up a common shape.
What is the summer triangle?
This theory states that clouds of gas and dust gradually collapse under its own gravity, which spins faster as it shrinks.
What is the Nebular Theory of Solar System Formation?
This massive object in our solar system, where it is impossible for anything to escape. It is the final stage of a massive star's life cycle.
What is a black hole?
This term contrasts two planets, with specifics such as their atmospheres and surface conditions.
What is Comparative Planetology?
In this phenomenon, the sky appears blue because red light is absent, and is absorbed.
What is Rayleigh Scattering?
Of Cepheus, Draco, Ursa Major, Cassiopeia, and Ursa Minor, this constellation is more commonly known as the queen on her throne.
What is Cassiopeia?
This philosopher, along with Galileo, believed in the more widely-know they theory that the sun is at the center of the universe, instead of the Earth being at the center.
Who is Copernicus?
In this type of star, two very close stars appear to be a single star that vary in brightness. The variation is caused by the star moving in front of another star.
What are Eclipsing Binary Stars?
This term describes gas and dust spinning faster and faster due to gravity. It also proves that the product of the rotation rate and the radius must be constant.
What is the Conservation of Angular Momentum?
In the 1800's, Lord Kelvin and Hermann Helmholtz believed they have correctly explained that the sun did this phenomenon, giving the sun a theoretical lifetime of 25 million years, which is now proven to be false.
What is Gravitational Contraction?
