    1. A13 billion years
    2. B14 billion years
    3. C13 million years
    4. D14 million years
  2. 2Who were the most influential figures in the history of astronomy?
    1. AKepler and Brahe
    2. BEratosthenes and Ptolemy

    4. DSocrates and Aristotle
    5. EAll of the above
  3. 3[blank_start]Eratosthenes[blank_end] was the first to measure the [blank_start]circumference[blank_end] of the Earth which helped to prove the Earth wasn't flat. Copernicus developed the heliocentric system and believed in [blank_start]perfect circle[blank_end] revolutions of the planets. Ptolemy's discoveries include developing the Ptolemaic universe model which was [blank_start]earth-centered[blank_end], [blank_start]epicycles[blank_end], and cataloging 1028 stars positions. [blank_start]Brahe[blank_end] is responsible for [blank_start]Tycho[blank_end]'s quadrant which is [blank_start]1/4[blank_end] of [blank_start]an arch[blank_end], used to measure positions, precision of the angular observant, and [blank_start]one[blank_end] second of [blank_start]an arc[blank_end]. The [blank_start]ellips[blank_end] orbit was discovered/hypothesized about by [blank_start]Kepler[blank_end]. Galileo discovered [blank_start]sunspots[blank_end], mountains and valleys on [blank_start]the moon,[blank_end] the [blank_start]four[blank_end] moons of [blank_start]Jupiter[blank_end], phases of [blank_start]venus[blank_end], and used the first telescope as a scientific instrument. Kepler is also responsible for [blank_start]3 laws[blank_end]. The first is that planets have elliptical orbits. The second is that when a planet is [blank_start]closer[blank_end] to the sun it moves [blank_start]faster[blank_end] than when it is [blank_start]further away[blank_end], and the [blank_start]third[blank_end] is that you can measure the [blank_start]orbit[blank_end] period of a planet that orbits around the sun and convert it to [blank_start]Earth years[blank_end] and then [blank_start]square[blank_end] it and the [blank_start]cubed root[blank_end] will be it's [blank_start]AU[blank_end] from the sun.

  8. 8Retrograde motion as explained by the [blank_start]Ptolemaic[blank_end] system is where the planets orbited around the [blank_start]Earth[blank_end] but also [blank_start]orbited around[blank_end] a fixed point within a smaller [blank_start]orbit[blank_end] similar to how the [blank_start]moon orbits Earth[blank_end] and [blank_start]Earth orbits the sun[blank_end]. The [blank_start]Copernican[blank_end] system explains retrograde motion by claiming the [blank_start]planets[blank_end] orbited around [blank_start]the sun[blank_end] in [blank_start]perfect circles[blank_end].
