Comet C/2022 E3 (ZTF), also being referred to as the ‘Green Comet’, is already being hailed as the best comet of 2023.
Last visible from Earth during the Stone Age, the comet, which made its closest approach to the Sun on 12 January, is now heading for its closest approach to Earth on Wednesday 1 February.
From the northern hemisphere, the comet is already visible in the night sky using a telescope or some binoculars.
However, as it gets brighter and closer, the comet could become visible to the naked eye against dark skies, making this potentially an exciting event for anyone without equipment keen to see a once-in-a-lifetime comet.
It made its closest approach to the Sun on 12 January 2023. After rounding the Sun, the comet continued to grow brighter towards the end of January.
Comet C/2022 E3 (ZTF) is due to be closest to Earth on 1 February. This will also be the moment the comet appears at its brightest, and currently it is hoped it will reach a brightness magnitude of +6. That would mean it would be visible to the naked eye.
