Scientists have found 30 exocomets in a young planetary system and measured their nuclei for the first time

An international team of researchers for the first time in the world discovered 30 exocomets and determined the size of their nuclei,

said in a press statement.

The prefix "exo", used before comets,means the fact that these space rocks were discovered outside of our solar system. Just like the 5,000 exoplanets that orbit other stars.

New batch of exocomets discovered in orbitstar system β Painter. Astronomers have been observing it for over 30 years as it contains a planetary system in the process of formation. In 1987, the first exocomets were discovered in it, located at a distance of about 63.4 light years from Earth.

A new study describes the discovery of 30 newexocomets and also provides the most detailed analysis of interstellar space rocks. Looking at observational data collected over the course of 156 days by NASA's Transiting Exoplanet Survey Satellite (TESS), the team used photometry to obtain new high-precision readings.

“Until recently, observations of β Pivotz were carried out only with the help of spectroscopy. Using high-precision photometry, we were able to study the dust tails of comets,” the scientists explain.

The team was able to determine the size of the nuclei of theseexocomet. It turned out that they ranged from 3 to 14 km in diameter. They were also able to measure the size distribution of exocomets, for the first time outside our solar system.
