What is the weather like on Venus and Mars?

Venus and Mars have weather as we know it. Because Venus's axis is barely tilted, it lacks seasonal changes: it is hot at all times. The atmosphere is 95% carbon dioxide, which heats the surface of Venus through the greenhouse effect, with an average temperature of 885°F (457°C).

Venus’ surface pressure is 90 standard atmosphere (91,192 millibars), while Earth’s surface pressure is 1 standard atmosphere (1013 millibars), with violent easterly winds blowing at 200 miles per hour (322 kilometers per hour). It orbits Venus at a speed that causes strong winds there. Light pours through thick sulfuric acid clouds, making Venus sparkle in the night sky.

The Martian atmosphere contains 95% carbon dioxide, but it has a relatively small gravitational pull. Much of its original gas has been blown away by the solar wind. The average surface pressure on Mars is 0.008 standard atmosphere (8 millibars). Low air pressure, combined with extreme dryness, prevents water from forming and accumulating. This means Mars has almost no clouds, and its thin atmosphere also makes Mars quite sensitive to heat from the sun: for example, temperatures at the equator range from -193°F to +72°F (-125°C to +22°C) year-round. change. Ice covers the poles of Mars, and their melting and freezing is affected by the planet's distance from the sun and by winds reaching speeds of 125 miles (200 kilometers) per hour, which create powerful dust clouds that block Sunlight slows down the melting of ice. These dust storms often invade the entire star.
