- What is a "hot Jupiter" Group of answer choices Exoplanets that are warmer than Jupiter. Exoplanet that are giant like Jupiter but orbits very close to their star. Any planet that is hotter than Venus. Jupiter size planets orbiting around stars much hotter than the Sun.INVEST IGATION 3 1. Fill out this data table with information you have collected (from Handout B: Pluto) about the dwarf planet Pluto. Characteristics Unit Pluto Mass 1024 g 14.6 Volume 1024 Cm3 7 Density g/cm3 2.08 5,900.4 Distance from Sun 106 km 1,185 Radius km Crust Thickness km unknown Atmosphere Height km 60 km Axial Tilt degrees 122.5 Force of Gravity on a 1 kg test mass Length of Day hoursImagine that you visit a planet orbiting another star and discover that it is heavily cratered, but its small moon is nearly crater free. Why would that be a surprise? Speculate what might have happened to those objects.
- Which of the following could the Close Encounter hypothesis NOT explain A)The planets all orbit in the same place B) The planets all orbit in the same direction C) Terrestrial planets do not have the same composition as the Sun D) All of theseWhy are jovian planets so much larger than terrestrial planets?
