The distance from Earth is about 6,500 light years (2000 parsecs).

Depending on where Mercury is relative to the Earth as the two planets orbit the sun, the distance from Mercury to Earth varies from 77.3x106km to 221.9x106km.
407,000 kmThe distance between the Moon and the Earth varies from around 356,400 km to 406,700 km at the extreme perigees (closest) and apogees (farthest).
The two points and the centre of the earth define a plane, and the intersection of this plane with the surface of the earth is a circle - the "Great Circle". The shortest distance between the two points is the smaller of the two arcs on this circle.

The Crab Nebula is too far away for its energy to have any impact on Earth.

The star that created the Crab nebula exploded in the year 1054
The crab nebula is estimated to be about 6,300 light year away.
The Crab Nebula is about 6,500 light-years away from Earth. Since one light-year is the distance light travels in one year, it took 6,500 years for the light from the Crab Nebula's explosion in 1054 to reach Earth.
The crab nebula has a diameter of about 11 light years. For comparison, the distance from the Sun to Neptune is only 0.000474385765 light years.
It was first observed by Chinese astronomers in 1054 AD, but given it's (estimated) distance from earth of 3,600 light years, the actual explosion would have taken place 3,600 years earlier, or around 2,500 BC.
It's difficult to be precise because of the great distance from us (~6,500 light years). It either lies on the rim of the Orion arm or the rim of the Perseus rim. [See related link]
