Its name is HD 63433d. It orbits HD 63433, a star about 73 light years away from our sun and part of a group of stars moving together that make up the constellation Ursa Major, which includes the Big Dipper.

HD 63433d is a recently discovered planet. A planet closer and younger than any other Earth-sized world yet identified. It was described in a new study published in The Astronomical Journal. Melinda Soares-Furtado and Benjamin Capistrant, co-led and co-wrote the study, both at UW-Madison.

“On a dark night in Madison,” Soares-Furtado says, “you could see [HD 63433] through a good pair of binoculars.” She continued, “This is our solar backyard, and that’s kind of exciting. What sort of information can a star this close, with such a crowded system around it, give away?”

To learn more about deep space, there are local options:

  • MMSD Planetarium, 201 S. Gammon Rd., Madison
    The Madison Metropolitan School District has public events during the school year.
  • Washburn Observatory, 1401 Observatory Dr., Madison
    The public is regularly invited to peer through the telescope.
  • Yerkes Observatory, 373 W. Geneva St., Williams Bay
    Wisconsin’s most famous observatory, Carl Sagan did his graduate work here.
