In a nutshell, global warming gone mad. Although Mercury is closest to the sun it doesn't have an atmosphere to keep in the heat and has a temperature variation of -170 to +420 degrees. Venus on the other hand has a very dense atmosphere consisting mostly of carbon dioxide, which has trapped the heat in. This has raised the temperature on the surface of Venus to over +460 degrees.

Which planet in our solar system has the lowest temperature?

That's rather a difficult question. Since we have explored so few planets, we have no way of making a totally accurate statement. It is presumable that the further away from the sun a planet is, the colder. By this logic, it can be said that Sedna is the coldest body in the solar system. However, since we have not explored the Oort Cloud, we cannot make a more informed estimation or measurement.
