While the asteroid will not pose a threat to earth or the moon, it will be at a close distance. At 1p.m. eastern time, the asteroid will be at it’s closest point to earth at 302-thousand miles. For perspective, the moon orbits at just under 240-thousand miles.
There is some controversy as to whether it’s an asteroid or a comet. Scientists originally thought it was an asteroid, but recently some experts think it may be a dead comet. This is a comet which no longer has any ice or water on it’s surface.
