Dark, sticky QE2 asteroid to pass by Earth on June 1

Huge asteroid will miss earth … by a few million kilometres

It is 2.7 kilometres long. Its surface is covered in a sticky black substance similar to the gunk at the bottom of a barbecue. If it hit Earth it would probably result in global extinction. Good thing it is just making a flyby.

Nasa lays out wild plan to corral asteroid

Nasa lays out a plan to launch an unmanned spacecraft on a mission to 'capture' a small asteroid and drag it near the moon, where astronauts can visit it.

Obama administration officials said the operation had the potential to jump-start a human exploration programme that had floundered since the 2011 retirement of the space shuttle. The White House will include US$105 million to begin work on the project in its 2014 budget.

Hold on to your hats: an asteroid will zoom within spitting distance of Earth next week, in what Nasa said on Thursday is the closest flyby every predicted for an object this large.

The last year DA 14, discovered by chance by astronomers after passing nearby last February, will be just around 27,700km above Earth’s surface when it speeds by, the US Space Agency said.

An asteroid missed the Earth on Tuesday. It was large. In astronomical terms, it was also close at just 1.4 times the distance of the moon. Had it hit Hong Kong, there would be no city left and it would have dried out the surrounding sea.

Asteroids and the end of the world

Calm down folks, stop the packing, cancel the spaceship order. Asteroid 1997 XF11, discovered last December by minor planet watchers and predicted mid-week last week to be set to send us to oblivion in 2028, may not hit Earth after all.
