- When you step from the shade into the sunlight, the Sun’s heat is as evident as the heat from hot coals in a fireplace in an otherwise cold room. You feel the Sun’s heat not because of its high temperature (higher temperatures can be found in some welder’s torches), but because the Sun is big. Which do you estimate is larger, the Sun’s radius or the distance between the Moon and Earth? Check your answer in the list of physical data on the inside back cover. Do you find your answer surprising?arrow_forwardAs an aspiring science fiction author, you are writing about a space-faring race and their home planet, Krypton, which has one moon. This moon takes 1,702,948 seconds to complete an orbit around Krypton. If the distance from the center of the moon to the surface of Krypton is 462.5 x 106 m and the planet has a radius of 37.2 x 106 m, calculate the moon's centripetal acceleration. Your Answer: Answerarrow_forwardA mini satellite weighing 50 kg is going to be launched into an orbit around earth by arocket. One sidereal day (period of earth’s self-orbit) is 23 hours, 56 minutes and 4.1seconds. (a) The rocket is to be launched from a platform in the Mongolian Plateau with a heightof 3.5 km above earth surface. Calculate the acceleration due to earth’s gravity atthis elevation.(b) The satellite shall complete 10 orbits in precisely 1 sidereal day. Calculate theorbital height and orbital velocity of the satellite.(c) Once the satellite is in this orbit, what is the acceleration due to earth’s gravityexperienced by the satellite?(d) Referring to your answer in part (c), explain why the satellite does not fall towardsearth as a result of earth’s gravitational pull?(e) Calculate the total energy of the satellite in orbit, using infinity as frame ofreference.(f) Calculate the escape velocity to leave earth’s gravitational well.arrow_forward
- In astronomy what does it mean when asked about the altitude when it comes to the moon?arrow_forwardA satellite orbits in the equatorial plane so that it is always above the same point of Earth's surface. How far away is it from the center of Earth? (The solution is 42.3×10^6 m)arrow_forwardOn the surface of the Moon an astronaut has a weight of Fg = 190 N. The radius of the Moon is Rm = 1.74 × 106 m, the gravitational constant is G = 6.67 × 10-11 N (m/kg)2 and the mass of the Moon is Mm = 7.35 × 1022 kg.
