Interstellar Asteroids Trapped by the Sun and Jupiter Could Deliver Alien Life to Our Solar System

  Interstellar Asteroids Trapped by the Sun and Jupiter Could Deliver Alien Life to Our Solar System There could be thousands of rocks from distant solar systems just killing time in our neighborhood.The high number is the result of the inexorable tug of the two largest objects in our neighborhood, the sun and Jupiter. "The solar system acts as a fishing net," co-author Avi Loeb, an astronomer at Harvard University, told Newsweek. "Just like when you go fishing with a net you catch some fish, the solar system can capture interstellar objects.

An asteroid the size of a football field is about to make a close pass by Earth but is not expected to hit or cause any damage, NASA said Wednesday. An asteroid nearly two miles (three kilometers) wide is set to pass by Earth Friday with no risk of impact, offering scientists a rare chance to study a

The "Super Bowl asteroid" garnered a lot of attention when it passed Earth right around the same time the big game kicked off Sunday. But another space rock is set to pass by much, much closer on Friday.

Asteroid 2002 AJ129 generated a lot of hype before it passed at a safe distance of about 2.6 million miles (4.2 million kilometers) Sunday. Part of the reason it got so much attention is that astronomers saw it coming. 

The more recently discovered asteroid 2018 CB, on the other hand, is smaller and will safely pass our planet at a much closer distance of about 39,000 miles (64,000 kilometers). NASA estimates the asteroid to be between 50 and 130 feet (15 and 40 meters) across. 

Dinos ‘too successful for their own good’

  Dinos ‘too successful for their own good’ A study modelling how dinosaurs spread worldwide shows they may have been a victim of their own success. UK researchers believe they were already in decline before the killer asteroid hit because they had occupied every habitat on Earth.From their roots in South America, the dinosaurs migrated "in a frenzy of movement to cover the planet".Hundreds of different dinosaurs appeared, from the ferocious T. rex to the gigantic long-necked Diplodocus.But by the time the asteroid struck, killing them off, they were starting to decline, as they had ran out of space on Earth.

On Friday , February 15, astronomers will get an unusually good look at a near- Earth asteroid called 2012 DA14. So how rare is such an occurrence? NASA says 2012 DA14 won’t be making a close call like this for another thirty years.

"Although 2018 CB is quite small, it might well be larger than the asteroid that entered the atmosphere over Chelyabinsk, Russia, almost exactly five years ago, in 2013," said Paul Chodas, manager of NASA's Center for Near-Earth Object Studies. "Asteroids of this size do not often approach this close to our planet -- maybe only once or twice a year."  

You may recall that the Chelyabinsk bolide exploded when it hit the atmosphere above Russia, creating a shock wave that blew out numerous windows on the ground.

2018 CB also comes on the heels of another recently discovered asteroid, 2018 CC, which came within 114,000 miles (184,000 kilometers) of us on Tuesday.

It's important to remember that while these asteroids are coming relatively close in space terms, they pose no threat to us. But perhaps someone should check to see if they might intercept the trajectory of "Starman" behind the wheel of Elon Musk's Tesla Roadster.

Elon Musk's Starman, the mannequin driver of the Tesla Roadster SpaceX launched aboard its Falcon Heavy rocket, is taking a trip around our solar system, in a large elliptical orbit that will bring him relatively close to Mars, the Sun and other heavenly bodies.
