Pluto's unusual eccentricity and tilt is likely due to its interactions with neighboring Neptune and other giant planets, ...
Dwarf planet 2023 KQ14, Ammonite, has a stable orbit that challenges the hypothesis of the mysterious Planet Nine.
First, let’s compare the orbital characteristics of Pluto with those of other planets. Pluto has an orbital eccentricity (the degree to which its orbit deviates from a perfect circle) of 0.25, while ...
Normally when a medium-size star dies, it blasts away the bulk of material in its system. The Hubble discovery was surprising ...

Methane gas may signal an atmosphere or geological activity on a distant dwarf planet located at the outer edge of the Solar System. A research team led by the Southwest Research Institute has ...
Gaia-4b is the most massive planet known to orbit a low-mass star. Also, see an animation for Gaia-5b, a brown dwarf orbiting a low-mass star. They were detected by the European Space Agency’s Gaia ...
In our nearby stellar neighborhood, a burned-out star is snacking on a fragment of a Pluto-like object. With its unique ultraviolet capability, only NASA's Hubble Space Telescope could identify that ...
