Term Stars can end their lives in three ways, List Definition White Dwarf Neutron Star Black Hole
Term How a star ends its life depends on Definition It’s Mass!

## How are ages of star clusters determined?

By determining the mass of the main-sequence turnoff stars, we get the age of the cluster. The cluster age equals the main-sequence lifetime of the turnoff stars. This is one of the ways we have studied the age of the Universe and the formation history of the Galaxy.

## What do stars in clusters tell us about the various stages of stellar evolution quizlet?

All stars in a cluster have the same age and composition. Only their masses vary. They are an excellent way to test models of stellar evolution. After a 100,000 years, the most massive O-type stars have reached the main sequence and are fusing hydrogen in their cores.

## What type of stars live the longest?

The stars with the longest lifetimes are red dwarfs; some may be nearly as old as the universe itself.

## How many Earths fit Betelgeuse?

## How many Earths can you fit in Mars?

Mars is actually smaller than the Earth! The radius of Mars is 3,389.5 km, which is just over half that of the Earth’s: 6,371 km. If you assume they’re both perfect spheres, this means that you can actually fit about 7 Mars’s inside Earth!

## What is Neptune’s mass?

1.024 × 10^26 kg (17.15 M⊕)

## Can you walk on Neptune?

Astronomers have calculated winds blasting across the surface of Neptune at 2,100 km/hour. Deep down inside Neptune, the planet might have an actual solid surface. In short, there is simply no way one could stand on the “surface of Neptune”, let alone walk around on it.
