Green comet, LIVE: when and at what time can it be seen in the southern hemisphere

2023-02-01T16:42:21.451Z


It is approaching Earth for the first time in 50,000 years. How and where to see it in Argentina. The transmission minute by minute.


The

green comet

is approaching Earth for the first time in

50,000 years

.

This is one of the most anticipated astronomical sightings since the celestial body was first discovered nearly a year ago.

The

green comet

can be seen in

both hemispheres

thanks to its intense green glow, which is produced by the

melting of the ice in its nucleus

as it approaches the Sun. This caused it to release a

tail of gases and dust

, which is visible to the naked eye .

.

Named by scientists as C/2022 E3 (ZTF), the

green comet

 was

transiting in the orbit of Jupiter

and was discovered in March 2022 with a telescope from the Zwicky Transient Facility (ZTF) astronomical project, in California, United States.


What will the passage of the green comet be like?

According to NASA, the

green comet

last visited us in Neanderthal times.

This 2023 will come within

42 million kilometers

(26 million miles) on Wednesday, February 1 before receding again, probably not to return for

millions of years

.

The green comet was discovered just under a year ago.

Discovered less than a year ago, the harmless

green comet

is visible in the night sky only with binoculars or small telescopes, and possibly with the naked eye in the darkest corners of

the Northern Hemisphere

.

On its way,

it will grow brighter

as it approaches our planet and rises higher above the horizon until the end of January.

The best hours to see it will be shortly before

dawn

While many comets have graced the sky in the past year, "this one appears to be a bit

larger

and therefore a bit

brighter

and comes a bit closer to Earth's orbit," the comet and asteroid guru said. from NASA,

Paul Chodas

.

The

green comet

will pass between the orbits of

Earth and Mars

on February 1 at a relative speed of 207,000 km/h (128,500 mph).

Its

core

is estimated to be 1,600 meters (one mile) in diameter and its

tails

extend millions of kilometers (miles).

What gives the comet its green color?


Comets

are

cold

bodies

formed by dust, stones and frozen gases, which circulate at the limits of

the solar system

.

However, sometimes they feel attracted to the Sun King.

When this happens, the heat from the star slowly begins to evaporate, so

a cloud called a coma and tail forms around it

.


In this case, the

green color

is due to the gases it contains, it is caused by the presence of

diatomic carbon

that absorbs the sun's ultraviolet rays.

It's not projected to look as bright as the

Neowise of 2020 or the Hale Bopp

and Hyakutake of the mid to late 1990s.


But "it will be bright by virtue of its close pass to Earth ... Which will allow scientists to do more experiments and people to see a beautiful comet," said Karen Meech, an astronomer at the University of Hawaii.

So much so, that since it was discovered

, the brightness of this green comet has increased

drastically, which is why astronomers estimate that

between February 1 and 2 it could be visible without the help of instruments.


Green kite: when and at what time will it be seen

As we said, the

green comet

 began to be visible from the end of January and will continue to be so until mid-February.

There will be two different viewing periods.

From January 20 to 31, those who live in the northern hemisphere and different tropical latitudes had the opportunity to enjoy it. 

And

from February 1 to 10, it will be best seen in the southern hemisphere

, including

Argentina

.

The optimal time will be between 45 minutes after sunset and up to three hours later.

Especially, during the night

of February 4,

 it can be observed more clearly.

In Argentina, the trajectory of the green comet in the north

of the country

can be seen more easily .

For this reason, in other areas it is best to observe it with binoculars or small telescopes. 

“February 2 is going to be the day that passes closest to earth.

Between February 5 and 7 are good days to be able to observe it from the southern hemisphere.

Around the end of January, it was seen better in the northern hemisphere,” explained Diego Bagú, an astronomer at the National University of La Plata, in dialogue with sitioandino.com.ar.
