Venusis the second planetfrom the sun and has a temperature that is maintained at 462 degrees Celsius, no matter where you go on the planet. It is the hottest planetin the solar system. Mercury is closest to the sun, this is true. However, because of its proximity to the sun it lacks an atmosphere. Mercury's gaseous molecules reached escape velocity long ago and the atmosphere was 'burned off' leaving a vacant wasteland of rock with a similar surface to the earth's moon. There is nothing to hold in solar radiation, thus is flies out into space. Venus is a different story. Its atmosphere is primarily composed of carbon dioxide - the primary green house gas -, which acts like a one-way door. The solar heat enters, but it cannot leave. Thus, an oven is created. This is why Venus has no water. Pictures suggest that Venus once had an aqueous environment, but because of climatic changes and intense heat.... it evaporated.

  • What is the difference between inner and outer planets?
    What is the difference between inner and outer planets?
    The solar system comprises of the sun, planets, and some other objects orbiting around the sun. The planet is categorized into two; we have inner planets and outer planets. Out of eight planets orbiting the sun, four are known as inner planets because they are very close to the sun, i.e., Mercury, Venus, Earth, and Mars. The other four are known as the outer planets because they are very far from the sun, i.e., Jupiter, Saturn, Uranus, and Neptune. Another difference is that inner planets are also known as solid planets because they are made up of rock and as a result, they are cumbersome compared to outer planets. On the other hand, outer planets are made up of gases, and they are lighter planets, which means they move very faster than inner planets. Due to the closeness between the sun and the inner planets, inner planets are usually warm, but outer planets are often cold because they are very far from the sun.
