What is the safest planet besides Earth?

Venus with some terms and conditions.

The planet’s atmospheric pressure is 92 times more crushing than Earth’s and is made up of 96.5% carbon dioxide. The rest of the atmosphere is mostly nitrogen. There is practically no oxygen and only a small trace of water vapor. Venus spins so slowly that one night on Venus lasts 58 Earth days. However, the thick atmosphere forms a blanket around the planet and means that the day and night temperatures are the same, around 460 degrees Celsius, hot enough to melt lead.

An Earth-like environment on Venus

However, there is an Earth-like environment on Venus. As we go up, then, as mentioned above, the temperature and atmospheric pressure decrease.

The graph above shows how the temperature and pressure of Venus’s atmosphere vary with altitude.

Interestingly, at an altitude of about 50 km, both the temperature and atmospheric pressure are similar to those on Earth at sea level.

In fact, at this altitude, the atmosphere of Venus is the most Earth-like environment, other than Earth itself, in the Solar System.

The atmosphere of Venus consists of 97% carbon dioxide, which is denser than Earth’s atmosphere. Thus, a large enclosed space filled with a nitrogen/oxygen mixture (similar in composition to that of Earth’s atmosphere) would float high above the surface of Venus in the same way that a helium balloon floats on Earth.

Great, isn’t it?
