You’ll Be Able To See Jupiter, Saturn, and Mercury This Weekend
A “conjunction” of planets is when two or planets align in the night sky from Earth’s perspective, and because all the planets in our solar system orbit the Sun at different rates, a conjunction can be quite a rare occurrence—especially a triple conjunction.
The best time to view the triple conjunction is about 30 to 45 minutes after sunset on Jan. 10, however, the planets should be visible after sunset on Jan. 9 and Jan. 11 as well. Jupiter, Saturn, and Mercury will be in their triangular layout low in the southwest sky, so head somewhere with an unobstructed view of the horizon line.
Jupiter will be visible to the naked eye, but both Saturn and Mercury will be on the dimmer side.
