9 The discovery of Eris A Was not surprising, because the existence of a massive "Planet X" had been predicted nearly a century ago. B Was surprising, due to its "backwards" orbit around the Sun. C Was surprising, since we thought we knew about all large objects in the solar system. Was not surprising, because other Kuiper belt objects approaching the size of Pluto had already been discovered. D

Which of the following statements accurately describes our current understanding of the solar system? a. There are no metals in the solar system beyond Jupiter and its orbit. b. Terrestrial worlds are so small because their large atmospheres were stripped away in time by Jupiter. c. Jupiter and Saturn are made of strictly a combination of hydrogen and helium, and both objects lack a planetary core. d. Various ices can contribute to the mass of planetary cores if we are at a great enough distance from the sun.

2. On August 27, 2003, the planet Mars was at a distance of 0.373 AU from Earth. The diameter of Mars is 6788 km. a) Calculate the angular diameter of Mars, as seen from Earth on August 27, 2003. Give your answer in arcminutes.
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 =
