Question 8 The star Betelgeuse is about 520 light-years away, If the speed of light were twice its present value, how far away would Betelgeuse be? O 2080 ly O 560 ly O 260 ly O 1040 ly O 130 ly Question 9 Which of the following is the reason for an ocean of water under Europa's frozen surface? O Furopa had many icy comets crash into the surface bring water to the moon and melting the water as it fell into the core. O Furopa formed with an unusual amount of liquid water in the core and the coldness of space wasn't able to freeze it. O upiter's strong gravitational force is causing Europa to flex in its orbit, leading to an increase in internal heating O Europa's close proximity to Jupiter puts it into a gravitational tug-of-war with Jupiter's largest moon Ganymede. Question 10 How was Neptune discovered? O When a large comet broke up and hit the planet, the explosion was seen from Earth-based telescopes O From a large sky survey that identified the "blue-green" planet.

Kepler’s First Law: Elliptical Planetary Orbits: The solar system major planet in the most elliptical solar orbit is little Mercury, which is the closest planet to the Sun. At Perihelion, Mercury’s distance from the Sun (Rp) is 0.31 AU. At Aphelion, Mercury’s distance from the Sun (Ra) is 0.47 AU. The intensity of Sunlight (I) that a planet receives from the Sun is inversely proportional to the square of that planet’s distance from the Sun (R). in other words, I = Constant / R2. Calculate how much more intense the Sunlight received by Mercury is at perihelion (p) than at aphelion (a): Rp2 = Ra2 = Ip / Ia = Ra2 / Rp2 =
