Document Summary
Exploring venus: venus, unlike mercury has been visited by a number of probes, most recently magellan spent years in orbit in the 1990"s and gave us detailed radio maps http://www2. jpl. nasa. gov/magellan, currently esa" venus express is in orbit, http://www. esa. int/esami/venus_express/ Venus is a little further from the sun. Venus has very thick clouds, so radiowaves are used but that doesn"t give us that much detail (largescale structures can be seen) Venus: venus is the second planet from the sun. It is at a distance of 0. 72 a. u. ( 1 a. u. is the average. Earth sun distance of 149,000,000 km) . Since venus is closer, it will have a shorter orbital period - 226 days, and it receives more sunlight so it is hotter: venus in size and structure is very similar to earth. It has a similar diameter and is about 81% of the mass. 30% closer to the sun than earth is.
