Jun 14, 2022 · In fact, Venus likely had oceans many billions of years ago. As the sun gets older, it also gets hotter. Billions of years ago, the sun was colder than it is today. There was a time when Venus orbited within the sun’s habitable zone. As the sun got hotter, Venus also got hotter. Over time, its oceans boiled away.

Venus is the second planet from the Sun, and Earth's closest planetary neighbor. Venus is the third brightest object in the sky after the Sun and Moon. Venus spins slowly in the opposite direction from most planets. Venus is similar in structure and size to Earth, and is sometimes called Earth's evil twin.
Feb 15, 2022 · Planetary surface temperatures tend to get colder the farther a planet is from the Sun. Venus is the exception, as its proximity to the Sun, and its dense atmosphere make it our solar system's hottest planet. The mean temperatures of planets in our solar system are:

Credit: Source: NASA/Johns Hopkins University Applied Physics Laboratory/Carnegie. Being the closest, we might expect that Mercury should also be the hottest. Indeed its surface temperature can get up to a sweltering 430°C in those regions under the full glare of the Sun. Yet the title of hottest planet in the Solar System actually goes to Venus.
Apr 19, 2022 · Mars is the coldest of the inner rocky planets, and it orbits just outside the Sun’s habitable zone at an average distance of 142-million miles (228-million kilometres). At such a vast distance, it’s no surprise that Mars is colder than the Earth. Surface temperatures on Mars average at minus 80 degrees Fahrenheit (minus 60 degrees Celsius).
Jun 14, 2023 · The Earth. The Earth’s average surface temperature is about 60 degrees Fahrenheit or 15 degrees Celsius. Our atmospheric composition is about 78% nitrogen, 20-ish% oxygen, and then about less than 1% of a whole bunch of other gases. But Venus’s atmosphere isn’t like Earth’s. We know that on Earth, carbon dioxide acts as a greenhouse gas.
