Watch a comet come closest to the net in 50,000 years

A comet discovered last year will come closest to the Sun next week, providing an excellent opportunity to see it.

Comet C/2022 E3 ZTF was discovered in March 2022 by astronomers at the California Institute of Technology’s Zwicky Transient Facility when it was 397 million miles (640 million kilometers) from the Sun. Astronomers first thought C/2022 E3 ZTF was an asteroid, but its coma, the cloud of ice and dust surrounding its core, was observed soon after. By December 2022, the comet had developed a long tail as it was heated by the Sun.
