Last night, asteroid asteroid 2004 BL86 passed about 750,000 miles (1.2 million kilometers) from Earth.
Nothing to worry about however, that distance is about three times farther away than the moon.
It will be the largest asteroid to pass this close to Earth until asteroid 1999 AN10 flies by in 2027. Although, it isn’t really a huge asteroid, it would still cause a lot of damage if it were to hit us. The asteroid/comet that ended the dinosaurs was about six (6) miles across.
Although, if you are in the L.A. area and have a chance, you can visit Griffith Observatory. They have an exhibit that allows you to crash a meteor/asteroid/comet into the Earth and change the speed/composition, etc. It is kind of fun to crash things into the planet. They might have one or two hundred other things to do, but that is a fun one.
The asteroid orbits the sun every 1.84 years, so it will be by again if you missed it last night.
