This discovery marks the first known case of a compact planetary system with such a noticeable tilt between close planet ...

A new investigation into old Kepler data has revealed that a planetary system once thought to house zero planets actually has ...

We see some of our hottest temps when Earth is furthest from the Sun (aphelion) and coolest at the closest to the Sun ...

As the sun grew hotter, so did Mars, prompting much of its atmospheric carbon dioxide to rain out and ultimately get locked ...

Mercury moves super fast around the Sun, finishing its year in just 88 Earth days. The planet has crazy temperature swings, ...

Earth isn’t standing as straight as it used to—something has actually made our planet tilt, and it’s not great news.

When most of us think about theweather on other planets, we imagine extreme conditions—boiling acid rain, methane snow, or violent winds sweeping across barren landscapes. Yet, recent space missions ...

They have elliptical orbits and have axial tilts as well, so they, too, get analemmas, but they’re shaped differently. Mars, for example, is tilted by about 25 degrees, similar to Earth.

Saturn’s moon Titan has always stood out among the celestial bodies in our solar system. It is the only moon with a thick, ...

For most of the year, the Earth's axis is tilted either toward or away from the sun. That means the sun's warmth and light ...

Earth’s North Pole tilts closest to the Sun, causing the Sun’s highest sky position. “Solstice” means the Sun appears to stand still before changing direction.

So, it's not our distance from the Sun that determines the seasons, it's the Earth's 23.5-degree axial tilt, which reaches its maximum at 10:41 PM tonight.
