This hypothetical star could even be responsible for the bizarre orbits of specific TNOs like the dwarf planet Sedna, discovered in 2003, and those that move almost perpendicular to the planet’s ...

For a long time, however, it was not entirely clear whether the dwarf planet had formed in the asteroid belt or whether it had migrated inwards from the edge of the solar system. A research team ...

Thanks to rapidly advancing telescope technology, astronomers have detected more than 5,600 planets outside our solar system. These exoplanets, as scientists call them, are worlds of lava, and ...
