interstellar comet 3I/ATLAS is making its closest approach to Earth tonight, December 19, attracting the attention of astronomers around the world. A comet is a very rare space object that came from outside our solar system. It is only the third interstellar visitor observed by scientists.
The comet was discovered on July 1 NASA-funded ATLAS telescopes in Chile. Soon after its discovery, scientists confirmed that its unusual motion and path suggested it came from another star system. Before 3I/ATLAS, only two interstellar objects had been identified: 1I/’Oumuamua in 2017 and comet 2I/Borisov in 2019, space.com Informed.
How close will Comet 3I/ATLAS come to Earth?
Despite the excitement, the comet will maintain a safe distance from our planet. According to the European Space Agency, 3I/ATLAS will come no closer than about 1.8 astronomical units to Earth. This is almost twice the average distance between Earth and the Sun, or about 168 million miles (270 million kilometers).
Scientists have clearly stated that the comet poses no threat to Earth or any other planet as it passes through the inner solar system.
3i/Atlas: Why does tonight’s flight matter to scientists?
Although it is still very far away, this close approach is scientifically important. It provides astronomers with a rare opportunity to study the dust and gas as the comet’s ice warms as it approaches the Sun, providing insight into how comets form and how planet formation in other systems compares to the processes that shaped our Solar System. space.com,
Interstellar objects like 3I/ATLAS are like space messengers. They bring clues from distant parts of the universe to our cosmic neighborhood.
Global attention and new space images
In recent weeks, major space agencies and observatories have focused on tracking the comet. according to space.comNew images released by the Hubble Space Telescope and the Jupiter Jupiter probe show a fast-moving object racing through the inner Solar System.
Once its journey around the Sun is complete, 3I/ATLAS will continue on its path and eventually leave the Solar System forever, making tonight’s flyby a rare and valuable moment for science.
How and where to take a closer look
The comet’s closest passage can be followed online via a free livestream hosted by astronomer Gianluca Masi. Virtual Telescope ProjectWeather permitting, the livestream will begin at 4am UTC on December 20,
