Nadir

by Dominic Ford, Editor

The nadir is the point in the sky vertically straight below the observer's feet.

One of the most interesting planets in the solar system can be found there – the Earth. A telescope is not needed to see it since its disk is quite apparent to the naked eye, measuring 180° across. In fact, it is so large that it occults half of the sky.
