Where exactly did the Russian meteor come from?

Poring over crowd-sourced footage, researchers Jorge Zuluaga and Ignacio Ferrin from the University of Antioquia in Medellin, Colombia, were able to use "simple trigonometry to calculate the height, speed, and position of the rock as it fell to Earth," says BBC News. More importantly, the duo was able to find out where Russia's most famous meteor was likely born.

Using astronomy software developed by the U.S. Naval Observatory, Zuluaga and Ferrin gathered enough data to trace the meteoroid's origins in outer space. The information included the meteor's relative angle to the horizon, the shadows it cast, and video timestamps of the rock's screaming descent.

Based on its trajectory and speed — zipping through the atmosphere at an estimated rate of 13 to 19 kilometers per second — the Russian meteor appears to have originated from the Apollo family of asteroids, which are "well-known near-Earth asteroids that cross the orbit of Earth," says Discovery News:

Around 5,200 Apollo asteroids are currently known, the largest being 1866 Sisyphus — a 10 kilometer-wide monster that was discovered in 1972. Large Apollos are identified as being a significant risk to our planet, so the Chelyabinsk meteoroid acted like an Apollo warning shot. [Discovery News]

Pluto’s diameter is 1,485 miles.

11 And they had as king over them the angel of the bottomless pit, whose name in Hebrew is Abaddon, but in Greek he has the name Apollyon.

What’s the name in Dholuo... Obama?

He’s correct. Wikipedea indicates a mean radius of 1161km, for a diameter of 1451 miles, so an equatorial diameter of 1485 miles sounds about right.

Thanks for the diagram. I took a couple of astronomy courses in college a long time ago, and my dad was quite interested in it too, so when I was young out family did a little star gazing. I will relay the information to my 95 year old mother who was very interested in what was going on “the day of the asteroids”. She is not as sharp as she used to be, but this topic surely tweaked her curiosity.

Wonderful! I’m glad your mom will enjoy it.

Some of the best times with our family have been *looking up at night*. I don’t think you ever outgrow the awe of it all. :)

Probably a lost Bullet Bob from Super Mario Brothers landed in the area.

Yes, the warming earth attracted the asteroid much like a female cat in heat in a neighborhood.
We’ll see more swarming at us soon!
/ end bad joke.

It was my meteor. It was taken from my truck where I thought it was secure. The idiot that broke the lock off of my truck tool box did not realize what he had taken. When the pawn shop he went to told him it had no value, he tossed it in the storm drain. Due to fracking that was taking place nearby making the whole area quite flamable and some idiot tossing a lit cigarette into the storm drain 2 blocks away... well no need to explain it further. I know this has happened to many of you too. Thank goodness I had the meteor insured.
