What is the orbital speed of Venus

astronomy

Like Mercury, Venus is an Earth-like planet. There is also no major difference between Earth and Venus in terms of size. For this reason, it was previously assumed that Venus was a lush, life-friendly planet under its dense cloud cover. However, the first probes that were sent to Venus and analyzed the chemical composition of the atmosphere did not meet these expectations: the atmospheric pressure on the surface is about 92 bar (earth about 1 bar). The main constituent of the atmosphere is carbon dioxide, which leads to a very strong greenhouse effect. Temperatures prevail on Venus that even Mercury cannot reach.

A day on Venus lasts longer than a Venus year. The direction of rotation around its own axis is opposite to that of most other planets (hence the apparently large inclination of the axis of rotation. In fact, this inclination is only 2.64 °. In the table below, the supplementary angle to 180 ° is given). One can say that the sun rises on Venus in the west and sets in the east.
