Madyson Barber, a grad student at the University of North Carolina at Chapel Hill, was researching young transiting systems in space when she made a remarkable discovery.
Barber used data from NASA’s Transiting Exoplanet Survey Satellite to observe the brightness of stars over time. During the observations, Barber noticed some “little dips” in brightness, indicating that a “transiting” planet may be passing near Earth.
The planet, named IRAS 04125+2902 b, is estimated to be 3 million years old, which is considered “young” for planets, Barber said. Earth is about 4.5 billion years old and took an estimated 10 million to 20 millions to form. The next youngest known planet is about 10 million years old, Barber said.
“It’s about the same as a 10-day-old baby in human timescale,” she added. “So, super, super young in comparison to our home.”
Nicknamed “TIDYE-1b” by researchers, the new planet has been shown to have an orbital period of 8.83 days, according to a paper published Thursday in Nature. It has a radius about 10.7 times larger than Earth and has approximately 30% of the mass of Jupiter.
