An asteroid is whizzing past Earth on Friday - and it's traveling with its own moon in tow.
1998 QE2, as NASA has named it, will not come anywhere near enough to collide with our world.
The closest it will come is about 3.6 million miles away - that's over 15 times the distance to our moon. It will reach that point just before 5 p.m. ET.
But it's giving astronomers the "best look at this asteroid ever," NASA said.
Remember when woolly mammoths roamed the planet? No? Well don't worry if you missed the last ice age - scientists have moved one step closer to possibly bringing the beasts back to life with the discovery of liquid blood in a well-preserved mammoth carcass in Siberia.
Researchers from the Northeast Federal University in Yakutsk found the 10,000-year-old female mammoth buried in ice on the Lyakhovsky Islands off the coast of northeast Russia.
Scientists say they poked the frozen creature with a pick and dark liquid blood flowed out.
