- Some interplanetary properties. Use excel calculator to fill in the missing calculations. use mass of the sun Msol= 1.99 x 10^30 kgHow much would a 10lb bowling ball weigh on an exoplanet that was twice as massive as Earth but had the same radius? 1. 10lb 2. 40lb 3. 100lb 4. none of the aboveExplain why a massive, cool planet is more likely to have a thick atmosphere than is a less massive, hot planet.
- 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.How many orders of magnitude do you need to grow in spatial scale (size) to form a planet? Let's take the extreme ends of this scale, from a dust particle of radius a = 10-6m to the gas giant Jupiter (you can round up its radius to the nearest ten to keep it simple). What else has this difference in order of magnitude? Maybe pick something that's not a length scale. Be creative!What is an exoplanet? Group of answer choices A planet in our solar system beyond Pluto. Any planet with extra-terrestrial life. A planet in an extra-solar star system outside of our solar system. Objects in the solar system such as Pluto that were once considered planets but no longer are.
- Why do we think that planets in our Solar System were not formed out of the gaseous disk by direct gravitational collapse? Planets are formed in disks. Disks rotate too fast to collapse gravitationally to form planets. In disks that are not massive enough, tidal gravity of the central star prevents the disk gas from collapsing. The material in the disk orbits close to the star. This makes the disk too hot, and pressure support prevented the disk from gravitational collapse. The gravity of the forming planets was not enough to accrete gas.Why are we unlikely to find Earth-like planets around halo stars in the Galaxy? A. Halo stars formed in a different way from disk stars. B. Planets around stars are known to be extremely rare. C. Halo stars formed in an environment where there were few heavy elements to create rocky planets. D. Halo stars do not have enough mass to hold onto planets. Is the answer C? Since halo stars are formed early when the galaxy consisted of mainly hydrogen and helium, there are no heavier elements available to create Earth-like planets so just halo stars are formed? Thanks!Please list and describe the main differences between a planet and a dwarf planet. Why was Pluto re-classified from planets into dwarf planets?
- What is the best way to determine if a exoplanet has life inside it? Group of answer choices Detect the star the exoplanet is orbiting and compare it to the Sun. Detect the exoplanet and determine if it is in the habitable zone of the star. Detect the exoplanet and study the atmosphere of the exoplanet. Detect the exoplanet and determine its age to see if it is similar to the age of the Earth.Needs Complete typed solution with 100 % accuracy.Describe the Nebular Theory.
