NASA Asteroids announced on its Twitter page that the 7482 (1994 PC1), the closest asteroid in the world, will fly safely across the planet today at a distance of 1.2 million miles (1.9 million km). This is about five times the distance between the earth and the moon. Asteroid will have another close presentation on July 3 this year.

Why are these steroids called potentially dangerous steroids (PHA)?
Observations of objects close to 0.05 astronomical or 7.5 million miles[7.5 million km]are called dangerous asteroids. According to the International Astronomical Union, there are more than 1,500 PHAs.
How does an asteroid look like?
According to earthsky.org 7482 (1994 PC1), it illuminates by 10 degrees. This amount is smaller than the brightness of Venus and other stars that we see with our naked eyes in the sky. The site also helps to identify a 6-inch or more backyard telescope asteroid, but you should make sure there is no light pollution.
Last year, NASA launched its first mission to protect Asteroids. Named DART, it collided with a small moon called Dimorphos between September 26 and October 1. He hopes that the slightest touch will change the course of the moon.
Things that are close to Earth this month
According to NASA, for the next 100 years, no known asteroids will be in danger of colliding with the ground. NASA’s Planetary Protection website added:
