NASA telescopes in Chile have discovered a comet from interstellar space, making its closest approach in October.

Felton Davis offered thousands of strangers a close-up view of the Moon and planets orbiting New York City. Now he’s passing ...

What if Earth's orbit ventured as far from the Sun as Pluto and as close to it as Venus? Tina Smith's Face-To-Face With 'Shocked' Mike Lee Is A Proven Way To Confront A Bully ‘The Honeymooners ...

A NASA-funded telescope in Chile identified a comet from interstellar space on July 1, marking a significant astronomical ...

Earth will reach its aphelion—or the farthest point in its elliptical orbit around the sun—on July 3, making the strawberry moon one of the farthest full moons from our star, per Live Science.

Mars, for example, is tilted by about 25 degrees, similar to Earth. Its orbit is much more elliptical, however, and that dominates the analemma, making it more teardrop-shaped.

A newly discovered object called 2017 OF201, likely a dwarf planet, travels in an extremely wide elliptical orbit (yellow), a new study suggests. The orbit of the dwarf planets Sedna and Pluto are ...

Kaib previously published work that suggested Earth's orbit was altered by a passing star three million years ago. “We looked at the typical, run-of-the-mill flybys,” Raymond told New Scientist.

But while the orbit and tilt of the planet play their part, this is not the only factor involved. In fact, what analemmas are measuring really is how far local time (e.g. UCT) differs from mean ...

The Gregorian calendar has 365 days, but the Earth actually takes about 365.25 days to orbit the Sun. That extra quarter-day is why we have leap years — and why the solstice shifts between June ...

Resilience followed a longer, low-energy trajectory that carried it well past its target, using the moon's gravity to bring it back to an initially elliptical orbit and finally, using its ...

As astronomers study an exoplanet called K2-18b, conflicting research reveals how difficult it is to find evidence of life beyond Earth.
