(WXIA) - An asteroid the size of a 7-to-10 story office building is expected to slide past the Earth early Friday at an altitude of 35,000 miles from the surface.

The asteroid, designated 2012 TC4, was discovered less than a week ago by scientists. Experts said they do not expect any adverse effects from the asteroid.

According to NASA, the 20-to-30 meter wide asteroid will pass Earth at 20 percent of the distance from the Earth to the moon, or 0.2 LD.

Scientists have not said whether or not the asteroid would be visible at its closest approach to Earth, which is expected at about 12:30 a.m. ET, Friday.
