An asteroid with diameters between 22 and 49 meters will shoot pass Earth in a distance closer than Earth from the Moon on Tuesday, according to the US National Aeronautics and Space Administration (NASA).

"Will #asteroid 2011 ES4 hit Earth? No! 2011 ES4's close approach is 'close' on an astronomical scale but poses no danger of actually hitting Earth. #PlanetaryDefense experts expect it to safely pass by at least 45,000 miles (792,000 football fields) away on Tuesday Sept. 1," NASA Asteroid Watch posted Saturday on its Twitter account.

NASA estimates the asteroid's relative speed at around 8.16 km per second.

The last time asteroid 2011 ES4 fly by Earth was visible from ground for four days. This time, it will be closer to our planet than before with an estimated distance of 1.2 lakh km, closer than that of the Moon, which is 3.84 lakh km away from the Earth.

The asteroid listed as potentially hazardous asteroid was first discovered in the spring of 2011 and passes by Earth every nine years.

A "potentially hazardous asteroid" is currently defined based on parameters that measure the asteroid's potential to make threatening close approaches to the Earth, according to NASA.

Elon Musk set a coin-seized computer chip in a pig’s brain in an attempt to materialise the ambitious plans to create a working brain-to-machine interface.

He unveiled the pig named Gertrude to demonstrate his ambitious plans, reports BBC.

"It's kind of like a Fitbit in your skull with tiny wires," the billionaire entrepreneur said on a webcast. His start-up Neuralink applied to launch human trials last year.

The interface could allow people with neurological conditions to control phones or computers with their mind.

Musk argued that such chips could eventually be used to help cure conditions such as dementia, Parkinson's disease and spinal cord injuries.

But the long-term ambition is to usher in an age of what Musk calls "superhuman cognition", in part to combat artificial intelligence so powerful he says it could destroy the human race.

Gertrude was one of three pigs in pens that took part in Friday's webcast demo. She took a while to get going, but when she ate and sniffed straw, the activity showed up on a graph tracking her neural activity.

The processor in her brain sends wireless signals, indicating neural activity in her snout when looking for food.

Camera

On the rear-end, Samsung Galaxy M21 has a triple camera (48MP+8MP+5MP) series. The primary sensor features 48MP wide shooter at f/2.0 aperture. The picture quality of its main rear camera is attractive with proper sharpness, details, and color vibrancy.
