A new probe in development known as GIRO represents a low-cost step toward unlocking the secrets of the outer planets, all through the invisible pull of gravity.

Recently, researchers found an arrangement of planets around a star that (if we ever saw one in real life) would fall right on that thin line—one so improbable that spotting an example may be an ...

In classical (or "Newtonian") mechanics, which describes the motion of macroscopic objects (i.e., things larger than an atom, such as planets), gravity is sometimes called a central force.

One of the rare times multiple planets did align was back in the 1970s and 1980s, when the four gas giants—Jupiter, Saturn, Uranus, and Neptune—formed tidy and temporary ranks in deep space.

More than a 150 years ago, before Neptune was ever seen in the night sky, French mathematician Urbain Le Verrier predicted the planet’s existence based on small deviations in the motion of Uranus.

The elusive Planet Nine, which is theorized to be lurking somewhere in the outer reaches of the solar system, may not be a planet after all, a new study suggests.

Another factor in Planet Labs' rise was likely the coming arrival of the space company's fiscal third quarter of 2025 results, slated to hit the headlines on Monday, Dec. 9.

Gas planets are not the only example of celestial bodies that resist diffusion due to gravity. Like gas planets, “stars are just giant balls of gas,” said Knittle. “And they hold together.” ...

One common question people seem to have about the planets' orbits is why the planets are drifting away from the Sun, given the Sun's strong gravitational pull keeping the Solar System together ...

The stock of satellite company Planet Labs (NYSE: PL) was floating higher at double-digit rates over the past few trading sessions. All told, according to data compiled by S&P Global Market ...
