Florence, A Nearly Three-Mile-Extensive Asteroid, To Swing By Means Of Earth On Friday

The asteroid that currently poses the biggest threat to Earth, according to Chodas, is Asteroid 1950 DA.
The asteroid, named Florence, is an almost three-mile wide rock that will pass safely within about 4.4 million miles of Earth (7 million kilometers) at 8:05 a.m.
Other asteroids have passed closer to Earth than Florence, but few have been this big.
It will take a sample of the asteroid and — in a US space first — bring the sample back to Earth.
If you don’t have a telescope, you can watch the space rock online on The Virtual Telescope Project.
