Planets/Eccentricity Test

Keplers 3 Laws

1. Planets move around the Sun in elliptical orbits

2.a planet moves faster when it’s closer to the Sun and slower when it’s farther away

3. planets farther from the Sun take much longer to orbit it

Planets Characteristics

planets revolve around Milky Way, gravity depends on mass and distance

Eclipses

an oval the planets revolve around the sun in

Galaxies

Spiral, elliptical, irregular

Star

Gas being held together By gravity, Massive star will for a supernova that can turn into a black hole or a neutron star

Nuclear fusion

When gases are pushed together under great pressure produces heat light, And electric magnetic Energy

Celestial object

Any object above or outside or atmosphere

Big Bang theory

Idea that all matter in the universe compacted into small space which caused a large explosion, occurring 10 to 14 billion years ago

Earliest Atoms

Hydrogen and helium, atoms became organized into celestial bodies after big bang

accretion

When dust and glasses come together by gravity to form stars in planets

Electromagnetic Spectrum

Scientist study that energy of admitted by stars were Reflected by planets using this

Insolation

Intensity: Strength of sunlight, Duration: length of day, Greatest at equator less everywhere else

Effects of seasonal change

Earth travels around the sun, the angle of the Suns rays change in cyclic Pattern
