Mars approaches for Earth close encounter

Mars and Earth will approach each other for their closest pass in 59,000 years this evening, making the Red Planet the third brightest object in the night sky, outshone only by the Moon and Venus.

The BBC’s 'Sky at Night' presenter Sir Patrick Moore said Mars could be found easily as it would so bright in the south at midnight, it could not be mistaken.

Slightly earlier tonight at 10.50pm the Earth and Mars will be at their closest point for 59,000 years as the elliptical orbital path of the two planets take them to separation of just 35 million miles (56 million km) in one of the closest encounters of the two planets.

Mars will be visible for several weeks and some surface features, such as the planet’s southern ice cap, should be visible to anyone equipped with a small telescope.

Viewed from the UK, Mars which actually appears more orange in colour due to the earth's atmosphere, should be highly visible low in the southern sky close to the constellation of Capricornus.

Taking advantage of the particularly favourable planetary alignment, NASA, the European Space Agency (ESA) and Japanese space agencies have four missions en route to the Red Planet.

The ESA orbiter-lander Mars Express carrying the Beagle 2, some 32 million km from the Red Planet, is almost halfway to its rendezvous with Mars following its six-month journey.

The Mars Express orbiter blaster off on June 2 this year and Beagle 2 lander is expected to touchdown on the surface on December 25.
