Astronomical events in February 2023

February 1: passage of comet C/2022 E3 (ZTF)

The long-awaited “visit” by comet C/2022 E3 (ZTF) has its highlight on the first of the month, when it reaches its maximum brightness as it passes 42 million kilometers from Earth. However, on this day it will still not be possible to find it in the sky here in the southern hemisphere.


Brazilians: wait a few more days

While we don’t have the opportunity to see the comet at its brightest night, it does begin to appear in the Southern Hemisphere sky over the next few days.

On February 2, C/2022 E3 (ZTF) appears just above the skyline in the early evening and gets higher and higher as the days go by. Residents of the Northeast region will be able to see it first, and little by little it will spread its grace to the other regions, reaching the southeast and then the south.

For São Paulo observers, the 10 will be high in the sky between 7 and 9 p.m., close to Mars:

The problem is that, after the first one, the comet’s luminosity becomes increasingly dimmer. On the 10th, despite being in a great location for us, its brightness will be too dim to see with the naked eye. Therefore, the solution is to equip yourself with binoculars or a home telescope for this observation.

February 15: Venus conjunction Neptune

Tonight, starting at 19:25, the planets Venus and Neptune will be together in the sky, facing west. However, this is not a simple observation, as Neptune is not visible to the naked eye and requires at least binoculars to find it.

Furthermore, the conjunction occurs just above the horizon line and disappears in about twenty minutes. That is: only those who find themselves in higher places and far from cities full of buildings will have any chance of admiring this celestial encounter.

February 22: Jupiter and Venus close to the Moon

Venus and Jupiter begin to move closer this month, heading for a beautiful conjunction that happens in March. And, in the early evening of February 22, the Moon appears between the two planets just after sunset.
