Final Answer: They affect how fast they travel by if they are closer then they will go faster.

How do systems outside of Earth affect Earth?

Why does an object go faster as it gets closer to its star?

Claim- Kepler's 2nd law

Kepler's 2nd law-the speed of a planet traveling in an elliptical orbit around the sun. It states that a line between the sun and the planet sweeps equal areas in equal times.

Equal area = Equal time

The further away the star is the slower it will go

Connections-when the Earth gets closer to a star it will start to rotate faster

The closer the planet is to the star the faster it will go

How do stars produce elements?

Claim-Nuclear fusion

Temperature and Luminosity are the main things that determine where the star lands on the spectrum scale

Hotter stars are on the color blue because there further on the spectrum scale

Connections- when hydrogen and helium are fusing together it is a main sequence star

The hotter the stars are the bigger they will be

Nuclei fuse together to form new elements

What evidence is there for the Big Bang?

Claim-The leftover radiation from the CBM

Red Shift-the displacement of spectral lines toward longer wavelengths in radiation from distant galaxies and celestial objects

Two factors that keep a star’s surface in balance are pressure from the core pushes out and gravity pushes in on it

Hydrogen and helium were the only elements formed from the big bang

Connections- The stars in the galaxies

High energy radiation has cooled to microwaves
