 Nope. You've picked Venus, the solar system's sixth
largest planet in diameter and the brightest object in the
sky (not counting the Sun and the Moon). In addition to its
carbon dioxide atmosphere, Venus has several layers of
sulfuric acid clouds. Venus is nearly twice as far from the
Sun as Mercury, yet Venus' dense atmosphere causes its
temperature to be hotter than that of the closest planet to
the Sun. Venus has been visited by more than 20 spacecraft.
Mariner 2 was the first one to fly by in 1962.
