✨The nearest planet to Earth after Venus is Mars. It has a daytime temperature and atmosphere more like the Earth's than any other planet.
✨Mars is called the red planet because it is rust in colour. This comes from oxidized(rusted) iron in its soil.
✨The fourth planet out from the sun, Mars orbits at an average distance of 227.9 million km. It takes 687 Earth days to complete its orbit.
✨Mars is 6794 km in diameter and spins around once every 24.62 hours- almost the same as the Earth takes to rotate.
✨Olympus Mons, Mars's Volcano, is the biggest in the solar system. It covers the same area as the UK and is three times higher than Mount Everest.
✨The surface of Mars is dry, rocky and covered in dust. The wind blows up huge dust storms, sometimes covering the whole planet. Dust devils, similar to small tornadoes, often race across the surface of Mars.
✨Almost all the water on Mars is frozen in to ice. There are ice caps at the poles, and thinn cloud made of ice crystals in the sky. Orbiting spacecraft have found ice hidden beneath the surface.
✨Mars was probably warmer and wetter in the past. Spacecraft have spotted many dried-up riverbeds, gullies and lake beds, and the Mars Rovers, Spirit and Opportunity have found minerals that normally form in water.
✨The Mars Global surveyor spacecraft has discovered two gullies on Mars where water or mud may have gushed out on to the surface in the last few years.
✨In 2008, NASA's Phoenix lander confirmed the presence of water in the form of ice crystals just below the surface. The ice was found in a soil sample scooped from a 5cm deep trench nicknamed snow White.
✨Mars is the best known planet besides Earth. Studies have revealed a planet with a surface like a red, rocky desert- but there is also plenty of evidence that Mars wasn't always so desert like.

Ever Since Humans have looked into the sky, we have dreamed and wondered, what is that little glowing red dot in the sky, and what is it all about. Today we have some answers to that question.
The first successful flyby of Mars occurred…
