What is WISEPA J174124.26+255319.5?

WISEPA J174124.26+255319.5, often called WISE 1741+2553, is a very special object in space known as a brown dwarf. Brown dwarfs are like stars, but they are not big enough to shine very brightly or for very long. This one belongs to a group called spectral class T9, which means it is quite cool compared to other brown dwarfs.

Where is it located?

It is located in the constellation Hercules, a group of stars that looks like a hero from ancient stories. WISE 1741+2553 is very close to us—it is only about 15 light-years from Earth. That makes it one of the nearest known brown dwarfs to our planet.

How was it discovered?

Scientists discovered this brown dwarf using a telescope called WISE, short for the Wide-field Infrared Survey Explorer. Studying objects like WISE 1741+2553 helps us learn more about how stars form and what happens when they don’t grow big enough to become true stars. This nearby brown dwarf gives scientists a great opportunity to study its properties up close.

History of observations

WISE 1741+2553 was found in 2011. It was discovered using data from the Wide-field Infrared Survey Explorer (WISE). WISE is a NASA satellite that looks at space using infrared light. This telescope worked from December 2009 to February 2011. It helped scientists find many new objects, including this brown dwarf.

Three groups of scientists reported the discovery. One group used early WISE data and a special camera on a big telescope to study the object. Another group used strong telescopes in Hawaii to see if it had a companion object. They found that it was a single brown dwarf. The third group listed it with many other new brown dwarf systems found by WISE.
