Origin of the Moon

What is the current accepted theory for how our Moon formed?

• Captured from an asteroid

• Big collision from a Mars-sized object with Earth

• formed simultaneously with Earth from space debris

• Pieces of Mercury entered our orbit

What is an exoplanet?

• any planet larger than earth

• another name for a moon

• a planet outside our solar system

• a celestial body that may one day form into a planet

The Fission Theory states

• An asteroid struck Earth breaking off a chunk that became the moon

• The Earth and Moon were formed simultaneously from gas and dust

• A large piece of early Earth broke off due to Earth spinning much faster than it is today forming the Moon

• A random celestial body passed by Earth too closely and got trapped in Earth's orbit

All of the following are ways that exoplanets are discovered except,

• The Wobble effect

• X-Ray imaging

• Direct imaging

• The transit method or photometric

Which of the following is true of exoplanets?

• They are celestial bodies, most of which are orbiting stars

• NASA has successfully sent rovers to land on exoplanets to collect surface matter

• Only 213 exoplanets have been discovered to date

• There are exoplanets 5 in our solar system

The wobble effect is a way for scientists to identify exoplanets. However, the size of the planet does not effect the wobble of the star.

• True

• False
