An asteroid is going to hit the Earth. To calculate its distance it is observed from 2 diametrically opposite points A, B on Earth. The angle subtended at the asteroid by these two directions of observations is 2o. Given the diameter of Earth to be about 1.276×107 m. compute the distance of the asteroid.

Answer» An asteroid is going to hit the Earth. To calculate its distance it is observed from 2 diametrically opposite points A, B on Earth. The angle subtended at the asteroid by these two directions of observations is $2^{o}$ . Given the diameter of Earth to be about $1.276 \times 10^{7}$ m. compute the distance of the asteroid.
