Galaxies & Stars




Now it is time to take a closer look at stellar evolution. 

Stellar Evolution

Common Core Math:

Calculating solar flare arrivals
Mean, Median, Mode
Solar Wind Velocity


Apart from the Sun, the nearest star is Proxima Centauri, a red dwarf star located at a distance of 4.2 light-years away.

A light year is the distance light travels in a single year 9,460,528,000,000 kilometers. So the light we see coming from Proxima Centauri left the star 4.2 years ago. Even being the nearest star, Proxima Centauri is incredibly far away.

If the current space crafts available travel at a top speed of 17,500 mph, how long would it take to travel to Proxima Centauri?

Challenge #2:

The Milky Way is the galaxy in which we live here on Earth.  The diameter of the Milky Way galaxy is 100,000 - 120,000 light years.  Using current space crafts, how long would it take to travel from one side of the Milky Way to the opposite side?
