    Venus is the 2nd Planet of the Sun and is about 108,200,000 km or .72 AU from the Sun.
    A day on Venus is actually longer than its year at 243 Earth days, while its year is 224.7 Earth days.
    Venus does not have any Satellites (moons)
    Venus is the sixth largest planet in the Solar System. The diameter is Venus is 12,100 km, while its mass is 4.869e24 kg.
    The atmosphere on Venus is made up mostly of Carbon Dioxide (96%) and Nitrogen (3%).
    The temperature on Venus runs around 480 degrees C (900 degrees F). This is a fairly constant temperature due to the greenhouse effect and Wind speeds on Venus.

    Cool Facts:

    The clouds in the atmosphere are composed of sulfuric acid which causes the planet to reflect about 65% of the sunlight. Because of this, Venus is the 3rd brightest object in the sky. Only the Sun and moon are brighter.

    The atmospheric pressure on Venus is 90 times the pressure on Earth.

    The interior of Venus is very similar to that of Earth.

    The Sunrise of Venus rises in the West and the sun sets in the East.

    Venus is named after the Roman goddess of love and beauty.
    BUT... Lucifer is the ancient Greek name for Venus and this is what they called the planet. Lucifer actually means "filled with light" which of course is a very different name described in the Bible.

    Mariner 2 was the first spacecraft to visit the planet in 1962.
    The Venera 7was the first spacecraft to land on another planet and it landed in 1970.
    Magellan mapped the surface using radar in 1989.
