Ultrawide binary objects in the Kuiper belt may not have come from the earliest solar system, research suggests
Trying to understand the makeup and evolution of the solar system's Kuiper belt has kept researchers busy since it was hypothesized soon after the discovery of Pluto in 1930. In particular, binary pairs of objects there are ...
Observations detect the lowest mass ratio contact binary to date
Astronomers from China and South Korea report the detection of a contact binary system with an extremely low mass ratio of only 0.0356. The newfound system, which received the designation TYC 3801-1529-1, is therefore the ...
