Question

Which is the hottest planet of the Solar System? What are its properties? Do you expect some kind of life on it?

Answer 1

Venus is the hottest planet of the Solar System.

Properties of Venus are;

Venus is the second planet from the Sun, an average distance of 108 million km from the Sun, taking almost 225 days to complete one revolution around the Sun. All of the planets rotate counter-clockwise, but Venus turns clockwise on its axis. Its radius is 6,052 km . The gravity on Venus is 90% the gravity on Earth, so if you could actually walk around on the surface of Venus it would feel similar to earth.The temperature on the surface of Venus is a blistering 462 °C. That’s hot enough to melt lead! Furthermore, the atmospheric pressure on the surface of Venus is 92 times Earth pressure.it’s this thick atmosphere that acts like a blanket, keeping Venus so hot. Venus is covered by smooth volcanic plains, and its dotted with extinct volcanic peaks and impact craters.

Venus has no moons. Venus has a very thick atmosphere of CO2, which adds incredible pressure, and traps in the heat.

Life on Venus:

When spacecraft began studying Venus, it became clear that the conditions on Venus are extreme compared to those on Earth.

The fact that Venus is located closer to the Sun than Earth, raising temperatures on the surface to nearly 735 K (462 °C), the atmospheric pressure is 90 times that of Earth, and the extreme impact of the greenhouse effect, make water-based life as we know unlikely on the surface of the planet. However, a few scientists have speculated that thermoacidophilic extremophile microorganisms might exist in the lower-temperature, acidic upper layers of the Venusian atmosphere.
