It is the brightest object in the night sky other than the Moon.
The first spacecraft to visit Venus was Mariner 2 in 1962, but more than 20 have been in total so far.
The planet is covered in very thick cloud. The surface can only be seen using surface radar imaging.
The temperature at the surface is very high (up to 460 °C). This is because it has a very strong Greenhouse Effect.
It has no satellites.
