The planet Venus is not a nice place to visit. It is the hottest planet in the solar system. The heat on Venus is hot enough to melt lead. The pressure is 90 times the pressure on the planet earth. This pressure crushed the first few probes that were sent to Venus. It is believed that it may be possible to change Venus into a planet that is more like Earth. A micro-organism, like a bacteria, could be created to eat the Carbon-Dixoide and release oxygen and nitrogen. This would create an atmosphere that would cool the planet to a temperature where life could exist.
