Lost Comet ATLAS: Search for Fragments Continues in Solar System

Astronomers continue the search for fragments of comet C/2019 Y4 ATLAS, which broke apart in 2020. Initially anticipated to be a spectacular sight from Earth, the comet now presents a lingering mystery regarding the fate of its pieces within our solar system.

The Disintegration of ATLAS

Komet C/2019 Y4 ATLAS, also known simply as ATLAS, was first discovered in 2020. Shortly after its discovery, the comet began to fragment, breaking into multiple pieces. Since then, researchers have believed that these fragments may still be circulating within our solar system.

A Challenging Search

A recent study published in The Astronomical Journal details efforts led by Salvatore A. Cordova Quijano of Boston University to locate one specific fragment, designated fragment B. The search utilized the Lowell Discovery Telescope and imagery from the Zwicky Transient Facility. Prior observations from the Hubble Space Telescope also identified potential remaining fragments after the comet’s disintegration.

Did You Know? A space probe detected the comet’s tail even after it had broken apart.

However, the Boston University team’s search for fragment B has not yet yielded concrete results. This lack of detection suggests that fragment B is likely less than one kilometer in size, making it exceptionally difficult to detect with current observational equipment.

Implications for Understanding Comets

The disintegration of comet C/2019 Y4 ATLAS in 2020 occurred without close observation by astronomers, hindering a more thorough understanding of the event. The search for these fragments is important for gaining deeper insights into the structure of comets, the processes behind their fragmentation, and how these small objects interact within the solar system.

Expert Insight: The difficulty in locating these fragments highlights the challenges inherent in studying relatively small objects in the vastness of space, and underscores the need for continued advancements in observational technology.

The fate of this celestial object also raises broader questions about the potential number of other comets that may remain hidden within our solar system.

Frequently Asked Questions
