Not so far as we know. There are 9 major planets in the solar system, and only one moon, Saturn's great moon Titan, which is known to have an atmosphere. With the exception of the Earth, however, no other planets or moons in our solar system are expected to have living systems. Titan and the atmosphere of Jupiter, however, may have a complex soup of organic molecules including some amino acids and simple proteins in a pre-biotic state. But no one seriously expects to see bacteria or single celled life anywhere else but on Earth.
