The comet '3I/ATLAS', which came from outside the solar system, is expected to approach Earth to about 270 million kilometers on January 19.
Why it matters
The close approach of an interstellar comet is a significant astronomical event that provides a rare opportunity to learn more about the formation and composition of objects from outside our solar system.
Key Points
- 1Comet '3I/ATLAS' is from outside the solar system
- 2It will approach Earth to about 270 million kilometers on January 19
- 3This is a rare celestial event as the comet originated from interstellar space
Details
The article discusses the upcoming close approach of the interstellar comet '3I/ATLAS' to Earth on January 19. Comets from outside our solar system are extremely rare, with only a handful ever observed. '3I/ATLAS' was first discovered in 2019 and is the second known interstellar object to visit our solar system after 'Oumuamua in 2017. On January 19, the comet is expected to come within about 270 million kilometers of Earth, which is still a safe distance but close enough for astronomers to study its composition and behavior in detail.
