Move Over, Santa; An Asteroid Is Flying By Earth This Christmas Eve

If you're given that telescope a day early, you have a chance to see an asteroid fly past Earth this Christmas Eve. (Video via NASA)
The asteroid known as 2003 SD220 is almost a mile wide and racing at a relative velocity close to five miles per second.
Don't worry, though –– NASA says at its closest point, it'll still be 28 times the distance between Earth and the moon away from us. On the downside, you won't be able to see it with the naked eye.
