The planets in our solar system are all different, from composition to rotation speeds and orientation. The concept of how the planets are rotating at different speeds, around the Sun and on their ...

The Sun's rotation is a massive factor, and it is high time that astronomers consider it. The Earth and the entire Solar System depend on the Sun for warmth and gravity as it floats around in space, ...

The Solar System "family portrait" is the final series of 60 images captured by NASA's Voyager 1 that show six of our solar system's planets. The image represents the first time a spacecraft has ...

By contrast, our sun is about 1,000 times more massive than Jupiter. “So this is a very good clue that the 2M1207 system we studied formed differently than our own solar system,” Zhou explained.

From Mercury to Pluto (and maybe even Planet Nine), here are some of 2023's most intriguing discoveries about the planets, moons and other bodies in our solar system.

This “solar wind” permeates the solar system. The most conspicuous features on the Sun are aptly called sunspots. These dark splotches belong to the photosphere.

Instead, the barycenter of the Solar System lies a little outside of the Sun's surface. However, scientists have not been able to pinpoint exactly where this center lies.

Accounts of total solar eclipses throughout history can reveal how Earth's rotation has changed. Newfound documents may prompt a rethinking of the planet's motion as far back as the fourth century.

By studying the rotation of the inner and outer regions of galaxies such as M33, astronomers can deduce the influence of dark matter in deviations from the expected model (bottom line). However ...

For comparison, Jupiter in our solar system is about 4.5 billion years old. The planet, however, will not maintain these sizzling temperatures.
