- Neptune has a mass of 1.0 ✕ 1026 kg and is 4.5 ✕ 109 km from the Sun with an orbital period of 165 years. Planetesimals in the outer primordial solar system 4.5 billion years ago coalesced into Neptune over hundreds of millions of years. If the primordial disk that evolved into our present day solar system had a radius of 1011 km, and if the matter that made up these planetesimals that later became Neptune was spread out evenly on the edges of it, what was the orbital period (in years) of the outer edges of the primordial disk?arrow_forwardUse a distance of R = 1.48x10^11 meters for the distance between the earth and the sun. Use a mass of 1.99x10^30 kg to be 1 solar mass. For each of the different sun masses (as values of solar mass, aka 0.5 solar masses = 1x10^30 kg), as outlined in the lecture, calculate the period of the earth's orbit in days using Kepler's law for circular orbits (I double-checked it with these values and it works) and also calculate the corresponding orbital velocity of the earth. Questions: 1.) Using these values, and 6x10^24 kg for the mass of the earth, what is the strength of the gravitational force between the earth and the sun? 2.) If the earth were twice as far from the sun, what would be its period of orbit? 3.) Mars orbits the sun at a distance of 2.18x10^11 meters. How long is a Martian year, using Kepler's law for circular orbits?arrow_forwardSuppose an asteroid has a tiny moon orbiting around it (which does occur). If the moon is 1.1 km wide, is 142 km from the center of the asteroid (which is 36 km in diameter), and assuming the moon has a circular orbit around the asteroid of period 36 hours, what is the mass of the asteroid? m = kg [Note: Use exponential notation for your answer with a format "9.99E12" for 9.99 x 1012.] What would the radius of the orbit of the same tiny moon be if it had an orbital period of 50.9 hours? Give your answer in km: R = km What is the density of the asteroid? Recall that density is mass per unit volume. The volume of the asteroid can be calculated based on its diameter (assume it is spherical in shape). Р kg/m³arrow_forward
