Historical Models & Theory of the Universe
current model of the Solar System
What is heliocentric?
the two opposing forces that keep our Solar System together
What is gravity and inertia?
Determines the temperatures of the planets.
What is the distance they are from the Sun?
the atmosphere that the planets Jupiter, Saturn, Uranus, & Neptune all have (solid, liquid, or gas)
What is gaseous?
Follow a highly elliptical orbit around the Sun
What are comets?
name of the theory of how the universe began that has measurements of an expanding universe and background radiation as evidence
What is the Big Bang Theory?
the force that keeps planets in a straight line
What is inertia?
ONLY terrestrial planet known to support life.
What is Earth?
The type of core Jupiter, Saturn, Uranus, and Neptune have. (solid, liquid, or gas)
What is solid?
composed of ice, dust, and frozen gas
What are comets?
the Earth is the center of the universe
What is the geocentric model?
the orbit of Earth's moon changed
What would happen if the gravity of the Earth changed?
the smallest planet and the closest planet to the Sun
What is Mercury?
Smallest outer planet
What is Neptune?
thought to be leftover pieces of a planet that did not form
What are asteroids?
This is data to support the heliocentric theory of the universe
What is the distance of planet orbits?
Location of the Milky Way in the Universe.
What the Local Galaxy Group in the Virgo Supercluster in the Universe?
the second planet from the Sun, third smallest, known for being extremely hot, containing thick clouds, and Earth's twin.
What is Venus?
Solid core, hydrogen and helium gas, 11 times bigger than Earth.
What is Jupiter?
Small, celestial object most similar in composition to the outer planets.
What is a comet?
The motion of a planet going around the Sun or a moon going around a planet.
What is to revolve?
A comet orbits in the Oort cloud. Type of gravitational attraction for a comet compared to an asteroid.
What is less gravitational pull / attraction?
some contain craters, surface water, no atmosphere, thick atmosphere, volcanoes, closest to the Sun, coolest, smallest
What are the inner planets?
Two gases all outer planets are composed of.
What is Hydrogen and Helium?
Three near earth objects, besides planets and the moon
What are asteroids, comets, and meteoroids?
