Remnants of a Comet May Still Exist in Our Solar System

Key Takeaways

1. Comet C/2019 Y4 ATLAS broke apart into many pieces after its discovery in 2020.
2. Scientists are currently searching for a specific fragment known as fragment B using advanced telescopes.
3. The search for fragment B has been challenging due to its likely small size, less than one kilometer across.
4. Observations from the Hubble Space Telescope revealed multiple fragments still orbiting in the solar system.
5. The breakup of the comet raises questions about the presence of other comets in our solar system that may be difficult to detect.

In 2020, scientists found comet C/2019 Y4 ATLAS and they thought it would be a spectacular sight from Earth. Unfortunately, it broke apart into many pieces, and some scientists think that the pieces might still be floating around in the solar system.

Search for Fragment B

A recent study published in The Astronomical Journal, led by Salvatore A. Cordova Quijano from Boston University, aimed to locate a piece known as fragment B. They used the Lowell Discovery Telescope along with images from the Zwicky Transient Facility to assist in their search. After the comet’s breakup, observations were conducted using the Hubble Space Telescope, which revealed multiple fragments that could still be orbiting in our solar system.

Size Matters

Despite their efforts, no success was found, indicating that this fragment is likely smaller than a kilometer across. This size makes it hard to spot with today’s technology.

Additionally, when comet C/2019 Y4 ATLAS fell apart, astronomers could not observe the event closely, which hindered their understanding of the situation. Ultimately, the destiny of this space object brings up more questions, especially about how many other comets might be lurking in our solar system.
