Colosseum-Sized Asteroid Between Jupiter and Mars Discovered; Could This Be the Smallest Finding of NASA's James Webb Space Telescope?

With the help of the powerful James Webb Space Telescope (JWST) of NASA, a European astronomer team was able to pick up an asteroid that had the rough size of the famous Roman Colosseum. SciTechDaily reports that its length spans from 300 feet up to 650 feet. Such a finding could be the smallest sighted by the prominent telescope.

Colosseum-Sized Asteroid

According to Forbes, this object is the first one that has a sub-kilometer size and that was spotted within the Asteroid Belt situated between Jupiter and Mars. Such a remarkable finding suggests how the telescope is capable of picking up minute objects across the cosmos.

The team of astronomers utilized data from MIRI (Mid-InfraRed Instrument) calibration and, somehow, detected this minute finding along the way. While the particular asteroid may serve as an example of an object in the main asteroid belt that does not exceed the length of 1 kilometer, it is necessary for specialists to perform further observations in order to know more about its properties and nature.

Astronomer Thomas Müller from the Max Planck Institute for Extraterrestrial Physics shares how the team unexpectedly detected this tiny asteroid through the observation calibration of the MIRI, which is publicly accessible. Müller mentions that such measurements are among the first ones from MIRI that aim at the ecliptic plane. The researchers' work suggests that several other objects can be picked up through the instrument.

Such findings were included in the Astronomy & Astrophysics publication.

Studying Tiny Asteroids

This asteroid discovery, which is suspected to be the smallest sighted by the JWST and one of the smallest found within the main asteroid belt, when confirmed, may have vital implications for understanding how the solar system forms and evolves. While present models are capable of predicting asteroid incidents that are minute, tiny asteroids have been looked into less thoroughly compared to bigger ones. This is because of how hard it is to observe these small objects. However, further observations through the JWST may enable specialists to look into asteroids that do not go beyond 1 kilometer.

The findings suggest that the JWST has the capacity to help detect undiscovered asteroids. The astronomers think that even short observations of MIRI, which are near the solar system's plane, will cover a few asteroids, with several of them being unknown ones.

To verify that the detected object is indeed a newly discovered asteroid, it is necessary to have more position data compared to background stars. This is necessary in order for the orbit of the object to be constrained.

JWST support scientist Brayan Holler says that the results are great and that they emphasize the MIRI's capacity to pick up asteroid sizes that used to be undetectable. Holler reports that observation replications are being scheduled. They are also expecting new asteroids to surface within such images.
