Beginning around sunset, Saturn will be situated closest to the horizon, followed by Mercury, Venus, Jupiter and Mars higher in the sky. While Neptune and Uranus also are within Earth’s line of sight, they’ll require binoculars or a telescope and are extremely difficult to locate, astronomers say.

It is being called a "planetary parade" as seven planets are expected to be seen in the Earth's night sky on Friday, astronomers said.

A stunning photo of a "parade of planets", shows Mars, Jupiter, Uranus, Saturn, Venus, Neptune, and Mercury in alignment from Earth. The image could be the first of its kind.
