It was only in March last year that scientists from Palomar Observatory In California, the glowing green piece of ice that will be on our land in the coming weeks flew by will. that C/2022 E3 (ZTF) It can’t be observed and documented in advance, it has a very simple reason: it takes too long for it to sun flew once. The last time I saw a piece of ice through a telescope They would have noticed, there wasn’t even that human civilization.
Now the comet is getting very close to us. on tour 42 million km Approaching the blue planet – that’s about 109 times so far He went like the moon. similar one rock bottom been for a while 50,000 years ago calculated.

42 million km in cosmic standards Just a stone’s throw away, which is why the snowball is also close with the naked eye It will be visible in the night sky.

This is good, because at about the same time the “green comet” also reaches the point closest to Earth: February 1, 2023. But the best time to watch it is probably now Jan 21 or the 20. Feb Being.

Also the European Space Agency ESA Presumably “modest instruments” would be needed to see the comet. Because despite its special color and proximity to Earth, C/2022 E3 (ZTF) cannot compare to bright comets like Neowise in 2020.
The culprit will be among January 20 and 22 It is much easier to find the inexperienced. For then he will stand “in a beautiful sky, Between the Big Dipper and the North StarPlus, C/2022 E3 (ZTF) is so high in the sky that it no longer decreases. So that we can see it in the sky all night long – provided we find it. This is still possible until around mid-February.
