A recently discovered comet will make an uncomfortably-close planetary flyby next year — but this time it’s not Earth that’s in the cosmic crosshairs.

According to preliminary orbital prediction models, comet C/2013 A1 will buzz Mars on Oct. 19, 2014. The icy interloper is thought to originate from the Oort Cloud — a hypothetical region surrounding the solar system containing countless billions of cometary nuclei that were outcast from the primordial solar system billions of years ago.

We know that the planets have been hit by comets before (re: the massive Comet Shoemaker–Levy 9 that crashed into Jupiter in 1994) and Mars, in particular, will have been hit by comets in the past. It’s believed Earth’s oceans were created, in part, by water delivered by comets — cometary impacts are an inevitable part of living in this cosmic ecosystem.

It’s believed Earth’s oceans were created, in part, by water delivered by comets — cometary impacts are an inevitable part of living in this cosmic ecosystem.

According to calculations by NASA’s Jet Propulsion Laboratory (JPL), close approach data suggests the comet is most likely to make a close pass of 0.0007 AU (that’s approximately 63,000 miles from the Martian surface). However, there’s one huge caveat.

Due to uncertainties in the observations — the comet has only been observed for 74 days (so far), so it’s difficult for astronomers to forecast the comet’s precise location in 20 months time — comet C/2013 A1 may fly past at a very safe distance of 0.008 AU (650,000 miles). But to the other extreme, its orbital pass could put Mars directly in its path. At time of Mars close approach (or impact), the comet will be barreling along at a breakneck speed of 35 miles per second (126,000 miles per hour).

Also, we don’t yet know how big comet C/2013 A1 is, but comets typically aren’t small. If it did hit, the impact could be a huge, global event. But the comet’s likely location in 2014 is also highly uncertain, so this is by no means a “sure thing” for Mars impact (Curiosity, you can relax, for now).

Astronomers predict a large-scale disaster on the Red Planet in October 2014, when a comet may ram into Mars, creating a 500-kilometer crater, the website of the Russian observatory ISON-NM said.

According to scientists, a catastrophe of global scale may occur on Mars. The trajectory of comet C/2013 A1, which Australian astronomers discovered in early 2013, will supposedly intersect with Mars. If it happens, the impact will produce an explosion, the power of which will be equivalent to 20 billion megatons of TNT.

The forecast is based on current measurements and will be updated as new data arrive. It was said that the comet was moving in the direction opposite to the planets of the solar system. Therefore, the speed in the possible impact will be very high – about 56 kilometers per second. The core of the comet is 50 kilometers large. A crater with the diameter of 500 kilometers may thus be formed on the crash site.

A comet near Mars may strike it in a powerful impact, potentially making the planet much warmer. The Red Planet is luring many entrepreneurs, including billionaire Dennis Tito, who aims to beat other nations by sending a man and a woman to Mars.

The make-or-break window for this possible game-changer is October 2014. At that time, an Oort cloud comet called C/2013 A1, first discovered last month, will approach Mars, missing it by about 35,000 km, which is quite close.

However the comet’s trajectory is still uncertain, which leaves a small chance it could impact the planet, said Russian astronomer Leonid Elenin, who worked on calculating the course of the celestial body. The comet will be travelling at a speed of 56 kilometers per second relative to Mars when it passes; if they do collide, the resulting explosion would be equal to a 20,000-gigaton bomb blast – powerful enough to leave a 50-kilometer crater on the planetary surface

The event would trigger a major change of the Martian climate, Australian space scientist Robert Matson explained. The impact would evaporate large amounts of water and carbon dioxide ice from the comet, spread across a planetary scale, making the climate on Mars much warmer due to the greenhouse effect.

On the other hand, the blast would also raise huge clouds of dust and could trigger volcanic activity in the mostly-inert planet. Both would make more sunlight bounce off the Martian atmosphere, which would make the planet colder. A heating effect is likely to prevail, however.

that would ruin titos little expedition now wouldn’t it?

i thought to be inhabitable..its has to be habitable first?..which it isnt..this is a meme..which may also play into something hitting earth as well as a theme..it wont make any difference to us if mars is hit..might make mincemeat of curiosity though!

  1. I thought Mars was already inhabitable? ;)

  2. Reblogged this on Ramy Abdeljabbar's Palestine and World News.

  3. Well when we get “attacked” by aliens, where will they be from, if Mars is dust?
