- If a detector on the surface of planet A displays a gravityacceleration of 4.9 m/s2, what is the mass of the planet withradius 2.5 x 106 m (in kg, G = 6.67 x 10-11 N (m/kg) 3?Scale 0.7707346 AU Period= 2.41495 Years Kepler's Laws: Using the orbit shown below and a ruler, measure the scale bar in the top left corner in centimeters. The length of the bar is equal to the distance in AU shown below the bar. Measure the aphelion and perihelion distance of the orbit inUsing the Vis-viva equation, calculate the total orbital energy of the satellite Mars Express given that it weighs 750 kg and is an orbit about Mars of eccentricity e = 0.571, Periapsis radius of 3687.5 km, Apoapsis radius of 13, 496.5 km.
- Please help me with this question. A=.2Kepler's 1st law says that our Solar System's planets orbit in ellipses around the Sun where the closest distance to the Sun is called perihelion. Suppose I tell you that there is a planet with a perihelion distance of 2 AU and a semi-major axis of 1.5 AU. Does this make physical sense? Explain why or why not.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.
- The NASA Kepler mission detected a transiting planet that blocks 1.3% of the stars light and the host star has a radius 82% of the Sun's radius (the Sun has a radius of 700,000 km) what is the radius of the exosolar planet in km?In early 2006, images from flybys of Enceladus showed something amazing, which explained the surprising findings from 2005. What was it?Please list and describe the main differences between a planet and a dwarf planet. Why was Pluto re-classified from planets into dwarf planets?
