First possible exomoon may change scientists’ idea of what a moon is

(NewsNation) — Astronomers may have discovered It’s the first moon outside our solar system, and it may force them to rethink the idea of what a “moon” is.

A. new study A paper published in Nature describes the discovery of a possible echotone, but things get a little weird. The researchers noted that the object could be an outer satellite or something else that does not fall entirely into the moon or planet category.

While Earth’s singular moon is the most familiar, 891 months Planets and dwarf planets orbiting in our solar system more than 200 only those belonging to Saturn.

Considering the numbers, it is reasonable to assume that planets in other solar systems travel with a similar environment.

But although NASA has documented more than that 6,000 exoplanets Since the 1990s, when the first world outside our solar system was discovered, outer moons have been difficult to find.

While using the Very Large Telescope (yes, that’s its real name) to examine a star system labeled CD-35 2722, scientists discovered an object that may be the first outer satellite.

Located 73 light-years from Earth, CD-35 2722 is a star roughly half the mass of the Sun. In its orbit is a brown dwarf, also known as a “failed star”. Brown dwarfs are huge compared to planets; They can be up to 80 times the mass of Jupiter, but are small compared to stars.

The newly discovered object is similar to the moon, but instead of orbiting a planet as moons in our solar system do, it orbits a brown dwarf.

This creates a three-tiered system that doesn’t fit neatly into existing concepts of what words like “planet” and “moon” actually mean.

The newly discovered object is large enough to be a planet, but it doesn’t orbit a star the way planets do. Instead, it orbits an object that is not a planet orbiting a star. This is what led scientists to consider it the first (possible) exomoon.

Officially the object has been labeled an exoplanet, and the discovery has now raised questions about what the moon is and how it can be identified outside our home system.

Researchers say the building is currently under construction. Extremely Large Telescope (also its official name) will help expand research into exomoons and exatellites, and various solar energy systems in the universe.
