The solar system ejects most of its comets like a gravitational slingshot, sending 95 percent into interstellar space—roughly 10,000 trillion...

At 25 light-years away, GJ 3378b feels distant—yet the Milky Way spans 100,000 light-years, making this super-Earth our next-door neighbor in cosmic...

Voyager 1 and 2 crossed the heliopause at almost identical distances—121.6 AU and roughly 119 AU—despite leaving through opposite hemispheres during...

Apollo astronauts placed corner-cube reflectors on the Moon in 1969, enabling laser ranging that measures Earth-Moon distance to millimeter precision....

An interstellar comet racing at 150,000 miles per hour on a hyperbolic orbit shows how vast solar system distances really are—its unbound trajectory means it will exit back into deep space after just weeks of visibility, not years.

NASA's Psyche spacecraft uses a Mars gravity assist to reach a metal asteroid in the outer belt.

GJ 3378b sits just 25 light-years away—our next-door neighbor inside the Milky Way's 100,000 light-year diameter—while receiving 90% of Earth's sunlight in the Goldilocks zone.

Today Earth reaches aphelion, its farthest point from the Sun at 152.1 million km, where orbital speed drops to 29.27–29.29 km/s. This 5-million-km...

GJ 3378b sits just 25 light-years from Earth, making it one of our closest cosmic neighbours in a Milky Way that stretches 100,000 light-years across....

GJ 3378b circles a red dwarf just 25 light-years away in Camelopardalis, ranking it among the nearest habitable-zone planets. Revised data show a...
