What is the first stage of a star's life?

Nebula

200

Why can't light escape a black hole?

The force of gravity is too strong

If the mass of one object is doubled, what happens to the force of gravity?

it doubles

300

What keeps the planets in orbit around the sun?

Gravity

300

What determines a star's life path?

mass

300

How do we detect black holes, if we can't see them?

By the effect they have on nearby objects

300

What is the name of the current program back to the moon and eventually to mars?

Artemis

300

It is divided by 4

400

Which is more dense Earth, or Jupiter?

Earth

400

What happens to low-mass stars at the end of their lives?

They become white dwarfs

400

List the three types of galaxies

Spiral, Elliptical, and Irregular

400

In what decades did the Apollo missions occur?

60's and 70's

400

What role does gravity play in star and planet formation?

It pulls and compressed all of the gas and dust particles together

500

What are the planets of our solar system, in order from closest to the Sun, to farthest?

Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune

500

What is one of the paths a star can take? Make sure to include at least three stages

Need at least three on one of the following two paths:

proto to main to giant to white dwarf

proto to massive star to super giant to super nova to neutron or black hole

500

What is the name of the galaxy closest to us and also on a collision course?

Andromeda Galaxy

500

What are the names of all three of the astronauts that were on the Apollo 11 mission?

Neil Armstrong, Buzz Aldrin, and Michael Collins

A student says the gravity depends on weight. Are they correct? Explain

No, weight is the force of gravity and changes based on where you are. Gravity depends on mass and distance. Mass is the amount of matter there is in an object.
