At its nearest approach, Venus comes within about 40 million km of Earth and the semi-major axis of the ellipse which is Venus' orbit is 1.08 × 108 km.
*How distant is Venus at its farthest in km?
At a given point, venus is 37.5 million miles from the earth. How long does it take for light to leave a source on earth and reach venus? give the answer in seconds. (the speed of light is 2.998x10^8 m/sec and 1 km= 0.62 miles)

- Like all planets, the planet Venus orbits the Sun in periodic motion and simultaneously spins about its axis. Just as on Earth, the time to make one complete orbit (i.e., the period of orbit) is what defines a year. And the time to make one complete revolution about its axis (i.e., the period of rotation) is what defines a day. The period of orbit for the Earth is 365.25 days and the period of rotation is 24 hours (1.00 day). But when these same values for Venus are expressed relative to Earth, it is found that Venus has a period of orbit of 225 days and a period of rotation of 243 days. So for Venus inhabitants, a day would last longer than a year! Determine the frequency of orbit and the frequency of rotation (in Hertz) on Venus.arrow_forwardVenus has an average distance to the sun of 0.723 AU.
