A potentially hazardous asteroid named 2014 JO25 flew past Earth just yesterday at safe but very concerning distance. This rock is as big as a tall skyscraper and looks like a peanut. Astronomers kept a close eye on this mysterious big asteroid and successfully captured it on cameras. Astronomers captured it on video with the help of Arecibo Observatory — a huge radio dish built inside of a Puerto Rican sinkhole.

Astronomers discovered the object some 3 years ago. As it came so close to Earth, it has earned the label of a "potentially hazardous asteroid," or PHA. Below is one of the primary radar videos that astronomers took of the asteroid using Arecibo on April 17th. According to NASA said the space rock will flew past Earth within about 1.1 million miles of Earth, or almost 4.6 times the distance from our planet to the moon, on April 19.
According to NASA it will come back to Earth after a little more than 400 years.
It is about 2,000 feet across. That's approximately between the height of the One World Trade Center in New York City and Shanghai Tower in China.
But according to Edgard Rivera-Valentín, a planetary researcher with the Universities Space Research Association who studies Arecibo data, said it may essentially be much larger than that.
