This body has the largest greatest elongation out of all bodies that do not exhibit quadrature relative to Earth.
This body has the largest greatest elongation out of all bodies that do not exhibit quadrature relative to Earth. The "black drop" effect was previously thought to be evidence for this bodies atmosphere. This body's 2012 occultation of a star, a consequence of its almost-8-to-13 commensurability with Earth, was used to refine existing techniques for studying exoplanet transits. The first successful flyby of this body, performed by the fourth in a series of (*) sixteen Soviet probes named for this body, discovered that it has a very weak magnetic field, which was later found to be induced rather than intrinsic. Uranus and this planet have retrograde orbits, and this planet's carbon dioxide atmosphere raises its surface temperature to well over 400 degrees Celsius. For 10 points, name this second planet from the sun.
