Some meteor showers happen at regular intervals because

• Other bodies in space spew rock at us in a regular pattern

• We pass through the orbit of destroyed comets orbiting the sun

• Remnants of comets revolve around the sun with Earth's orbit just at a slower speed

• Comets are launched into the solar system towards each from outer space at regular intervals

The Oort Cloud contains all the asteroids that take up the region of space between Mars and Jupiter

• True

• False

Which of these planets formed first in the formation of the solar system?

• Earth

• Venus

• Mercury

• All of them formed at approximately the same time

What is needed in order to form a solar system like ours?

What does it mean that the solar system is differentiated?

• The outer planets have much more heavier elements than the inner planets

• The inner planets have much more heavier elements than the outer planets

• The inner planets have much less lighter material than the outer planets

• The proportion of materials in the solar system is constant from the inner to outer planets

What kinds of exoplanets are more easily detected?

• Planets like Earth, small and in the habitable zone

• Planets like Saturn, that have rings so they are easier to spot with telescopes

• Planets like Mercury, which are closer in to their star

• Planets like Jupiter, but very close to their star
