Stargazers will be treated to a rare seven-planet alignment in February. This is what scientists hope to learn.

The seven planets will not be perfectly aligned, but will appear in an arc across the sky due to their orbital plane in the Solar System.

This January and February, a rare planetary alignment featuring Venus, Mars, Jupiter, Saturn, Uranus, and Neptune will be visible, with Mercury joining in late February for a seven-planet display. While planetary alignments have little impact on Earth,

Venus, Mars, Jupiter, Saturn, Uranus, and Neptune will align in a line in the sky. Although most of these planets will be visible to the naked eye, some require binoculars for observation. A planetary parade is a phenomenon that occasionally appears in the night sky when the planets of the Solar System form an apparent line in the sky.
