The D-1 Asteroid

Name: Doomsday-1

Designation: Asteroid

First sighted: 15/11/2012

Age: 4.8 billion years old

The D-1 Asteroid is the size of India. It is traveling at 38 km/s or approximately 136,800 km/h and has a density of 8000 kg/m^3 and is composed mostly of iron. It will strike the Earth at a 79 degree angle and it will impact in sedimentary rock.

Scientists predict that the Earth will be strongly disturbed by the impact, but will lose little mass. They predict that 100 percent of the Earth will be melted and this will be an extinction level event.

The impact may make a very small change in the tilt of Earth’s axis (< half a degree). The collision may cause a change in the length of the day of up to 32 hours. The impact does not shift the Earth’s orbit noticeably.
