[3] [16] [33] [46] Another variation on the rogue planet motif involves planets in the Solar System leaving their orbit around the Sun and becoming rogue planets drifting through space, as happens to the Earth by chance in Fritz Leiber's 1951 short story "A Pail of Air" and by design in Liu Cixin's 2000 short story "The Wandering Earth" and its ...
NASA has released the following images of a large asteroid as it readies to pass by alarmingly close to Earth on April 19.. The administration has been monitoring the space rock, known as 2014 ...
Motion interpolation of seven images of the HR 8799 system taken from the W. M. Keck Observatory over seven years, featuring four exoplanets. This is a list of extrasolar planets that have been directly observed, sorted by observed separations. This method works best for young planets that emit infrared light and are far from the glare of the star.
The researchers discovered asteroid 2024 MK just 13 days before it flew by Earth, zipping past at a distance of only 184,000 miles (295,000 kilometers) from our planet — just over three-quarters ...
