Students have asked these similar questions
If we moved Venus out to 1 AU from the Sun (same as Earth), Venus would probably
a.
become more like Earth, with oceans and a temperate climate
b.
remain hot, dry, and dead because it's permanently lost its oceans
c.
become more like Mars, losing most of its atmosphere and freezing
d.
become much less geologically active due to decreased solar heating
Estimate the distance between Venus and Earth in km and AU.
Express your answer using two significant figures.
Imagine you grew up on Mars, whose semi-major axis is 1.5 AU. In observing the planets over your lifetime from the Martian surface, what is the largest angular separation you would see between the Earth and the Sun? Take the orbits of the Earth and Mars to be circular.

- The Mars Robotic Lander for which we are making these calculations is designed to return samples of rock from Mars after a long time of collecting samples, exploring the area around the landing site, and making chemical analyses of rocks and dust in the landing area. One synodic period is required for Earth to be in the same place relative to mars as when it landed. Calculate the synodic period (in years) using the following formula: 1/Psyn = (1/PEarth) - (1/PMars) where PEarth is the sidereal period of the Earth (1 year) and PMars is the sidereal period of Mars. If 3/4 of a Martian year was spent collecting samples and exploring the terrain around the landing site, calculate how long the Mars Robotic Lander expedition took!arrow_forwardBased on this graph, what is the approximate speed of Venus in Km/s?
