  2. Mercury

    Mercury is the closest planet to the Sun and due to its proximity it is not easily seen except during twilight. For every two orbits of the Sun, Mercury completes three rotations about its axis and up until 1965 it was thought that the same side of Mercury constantly faced the Sun. Thirteen times a century Mercury can be observed from the Earth passing across the face of the Sun in an event called a transit, the next will occur on the 9th May 2016.Mass:

  3. Venus

    Venus is the second planet from the Sun and is the second brightest object in the night sky after the Moon. Named after the Roman goddess of love and beauty, Venus is the second largest terrestrial planet and is sometimes referred to as the Earth’s sister planet due the their similar size and mass. The surface of the planet is obscured by an opaque layer of clouds made up of sulfuric acid.

  4. Earth
    Earth is the third planet from the Sun and is the largest of the terrestrial planets. Unlike the other planets in the solar system that are named after classic deities the Earth’s name comes from the Anglo-Saxon word erda which means ground or soil. The Earth was formed approximately 4.54 billion years ago and is the only known planet to support life.
    Mass: 5,972,190,000,000,000 billion kg
    Equatorial Diameter: 12,756 km
    Polar Diameter: 12,714 km
    Equatorial Circumference: 40,030 km
    Known Moons: 1
    Notable Moons: The Moon
    Orbit Distance: 149,598,262 km (1 AU)
    Orbit Period: 365.26 Earth days
    Surface Temperature: -88 to 58°C
