Why is venus so hot?

And is thete a way to send a probe to look at the planet

Several probes have been sent to Venus. In 1962, Mariner2 came withing 34,400km of Venus. Venera 7 landed on Venus but failed within 1 hour because of Venus' high temperature. In 1982, Venera 13 transmitted the first color pictures from Venus' surface.

2)96% Of The Venus Atmosphere Is Carbon Dioxide, 3.5% Is Nitrogen.

Due To This Heat Get Trapped Inside ,Its Atmosphere,Heating Up The Planet,Just Like Green House Effect ,Here On Earth.

Because of its distance from sun if our planet was at that distance absolutely our planet had that temperature. Venus was like our earth but because of its distance lots of carbon di oxides produced and made green house gas. It s cause of the high temperature

It has a dense carbon-dioxide dominant atmosphere that holds in the heat through the greenhouse effect. Mercury is small, so small that it cannot hold much of an atmosphere.
