On the evening of an autumnal equinox day Siddhant noticed that Mars was
exactly along the north-south meridian in his sky at the exact moment when the sun was
setting. In other words, the Sun and Mars subtended an angle of exactly 90° as measured
from the Earth. If the orbital radius of Mars is 1.52 au, What will be the approximate rise
time of the mars on the next autumnal equinox day?
one trajectory that can be used to send spacecraft from earth to mars is an elliptical orbit that has the sun at one focus, its perihelion at earth, and it's aphelion at mars. the spacecraft is launched from earth and coasts along this ellipse until it reaches mars, when a rocket is fired to either put the spacecraft into orbit around mars or cause it to land on mars. (a) find the semimajor axis of the ellipse (in au). (hint: draw a picture showing the sun and the orbits of earth, mars, and the spacecraft. treat the orbits of earth and mars as circles.) [enter your answer in units of au]
A)At what altitude would a geostationary sattelite need to be above the surface of Mars? Assume the mass of Mars is 6.39 x 1023 kg, the length of a martian solar day is 24 hours 39minutes 35seconds, the length of the sidereal day is 24hours 37minutes 22seconds, and the equatorial radius is 3396 km. The answer can be calculated using Newton's verison of Kepler's third law.

- As 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_forwardThe average orbital distance of Mars is 1.52 times the average orbital distance of the Earth.

Are you going to experience the next visit?arrow_forwardThe earth revolves around the sun in exactly 365 1/4 days which is equivalent to 1 year. To make up for the loss of 1/4 day, the calendar was adjusted so that we have a leap year for every 4 years. If the earth were to speed in its motion slightly so that a year would be completed in exactly 365 days and 6 hours, how often would we need to have a leap year?arrow_forward
