Some worlds in the universe seem straight out of a cosmic fairy tale. Kapteyn b is one such world. Located just 13 light years away, this planet is fascinating not only because of its proximity, but especially because of its history. Imagine a world almost as old as the universe itself: that is Kapteyn b.
A planet nearly 11 billion years old
Kapteyn b orbits a red dwarf star called Kapteyn, a small but stable star that was once part of another galaxy. This galaxy was swallowed by our Milky Way billions of years ago. Kapteyn b is therefore a survivor of a lost galaxy. With an estimated age of 11 billion years, this planet is almost twice as old as our Earth. While our planet was still in its infancy, Kapteyn b already had billions of years of evolution behind it.
The mysterious habitable zone
What makes Kapteyn b even more fascinating is its possible location in the ‘habitable zone’ - the area around a star where water may exist in liquid form. Although we have no evidence yet for water or life, the location of Kapteyn b presents an intriguing possibility: could this primordial world once have housed life? Perhaps the answers are hidden in the atmosphere, waiting to be discovered.
A rough past
Kapteyn b's history reads like a cosmic adventure. Born in another galaxy, swept into the Milky Way, and now orbiting a quiet star, the planet seems to have weathered it all. This journey through the universe makes Kapteyn b not only unique, but also a valuable source of knowledge for scientists seeking to understand how planets evolved in the early days of the universe.
What can we learn from Kapteyn b?
Kapteyn b shows us how diverse and fascinating planets outside our solar system can be. Studying this planet can teach us not only something about the history of the universe, but also about the chances of life elsewhere in the cosmos.
