NASA Asteroid Alert A Space Rock will skirt past Earth on Tuesday evening.

Nasa has issued a “close approach” alert for the mysterious space object – and says it will even be joined by a second Earth-skimming asteroid on the same day.

The good news is that asteroids frequently pass close to Earth, so there is no need to panic.

In fact, NASA has designated ten “near-Earth objects” as making a “close approach” during the month of November alone.

As they orbit the Sun, Near-Earth Objects can occasionally approach close to Earth, the U.S. space agency explained.

It’s also vital to remember that a “close approach” may not be as close as you think.

The main asteroid on Tuesday is called 2013 CW32, and was (as the name suggests) 1st spotted in 2013.

It measures a massive 820 feet across, and is travelling at a very nippy 36,775mph.

It’s due to pass Earth on January twenty nine at about 6.54pm time, give or take a minute.

And it’s due to skirt us at a fairly safe distance of 3,119,690 miles – about fourteen times the distance between the earth and the Moon.

There’s actually a second asteroid passing Earth on Tuesday, too – but it is smaller.

Asteroid 2019 AN11 measures a less terrifying a hundred and seventy feet, and is travelling at a much slower (though hardly slow) 18,000mph. The 2019 in its name means it was 1st spotted this year.

It’ll skirt Earth at a distance of two,988,529 miles at about 5.50am UK time.

Sadly it is very difficult to see asteroids with a telescope, because they are often very little and faint – with varying levels of reflectiveness.

The best method for amateurs is astrophotography, that involves taking several photos of the night sky.

It’s possible to then compare the pictures and then look out for little objects that have changed position.
