The recent lunar eclipse had spawned countless doomsday theories; now here comes another one. Only this time it's not the moon but a gigantic asteroid that is expected to destroy the world, possibly as early as next week.

Televangelist Pat Robertson has predicted that a big asteroid would hit earth and destroy 'everything' and this could happen anytime next week.

Robertson predicted the end of the world during his show The 700 Club that airs on ABC Family. 'A giant meteor will bring an end to the world' is a prophecy by none other than Jesus Christ, news website rawstory.com reported.

"I wrote a book. It deals with an asteroid hitting the Earth. I don't see anything else that fulfills the prophetic words of Jesus Christ other than an asteroid strike," Robertson told viewers during the show.

"There isn't anything that will cause the seas to roil, that will, you know, cause the skies to darken, the moon and the sun not to give their light, the nations terrified on Earth of what's happening. There isn't anything that's going to do that."

"We're big enough to draw some of them in. And as somebody said, it's 'blind luck.' Well, it's the mercy of the Lord. But if that mercy ever got lifted, whew. That's what Jesus himself said!" he advised. "So, hey, just get ready. Get right. And stay right with the Lord."

"It could be next week, it could be 1,000 years from now. But nevertheless, we want to be ready whenever the Lord says, 'I'm wrapping it up, and it's time to come home."

Robertson is known to predict sensational disasters in order to publicise his books.

Asteroids entering the earth's atmosphere have increased remarkably in the last 14 years as more than 26 nuclear-sized explosions have been detected on the Earth's surface caused by asteroids.

The startling revelation was made by the asteroid-hunting organisation the B612 Foundation earlier this week. The report collected data from the nuclear missile detection system that picks nuclear blasts on earth.

"The fact that none of these asteroid impacts shown in the video was detected in advance is proof that the only thing preventing a catastrophe from a 'city-killer' sized asteroid is blind luck," said Ed Lu, member of the B612 Foundation.

The former NASA astronaut warned of the possibility of major asteroid attacks in the future as the Earth is getting more vulnerable to such strikes. Memories are still fresh of the huge meteor that fell out of the Russian sky last year; it had left around 1,200 people injured.

"Less than 10,000 of the more than a million dangerous asteroids with the potential to destroy an entire major metropolitan area have been found," Lu said.

"We live in a shooting gallery. The big ones have been found, but the smaller ones — we don't know. Just because it's not raining now doesn't mean it's not going to pour tomorrow."
