  Mysterious Interstellar Object Might Have Shifted Four Planets’ Paths, Study Finds

  A mysterious interstellar object, estimated to be eight times the mass of Jupiter, may have significantly altered the orbits of Jupiter, Saturn, Uranus, and Neptune billions of years ago. A study suggests that this body passed remarkably close to the Sun, potentially influencing planetary trajectories. Simulations conducted by researchers indicate ...

  Interstellar Object Could Have Shifted Trajectories of Four Planets, New Research Shows

  A recent study suggests that an interstellar object, possibly as massive as eight times Jupiter, may have passed through the solar system billions of years ago, significantly altering the orbits of its outer planets—Jupiter, Saturn, Uranus, and Neptune. Using computer simulations, researchers found that in about 1% of the scenarios, such a close ...

  Astronomers Discover Water and Carbon Dioxide in WASP-166 b's Atmosphere

  Astronomers have detected water and carbon dioxide in the atmosphere of WASP-166 b, a hot super-Neptune exoplanet. Using data from the James Webb Space Telescope (JWST), the findings also noted ammonia in smaller quantities. WASP-166 b, located 368 light-years away, is a massive planet that orbits its star every 5.44 days, with a temperature of 1,2...

  Discovery of Hidden Ninth Planet in Solar System Could Reshape Astronomy, Claims New Study

  Scientists are exploring the possibility of a hidden ninth planet in our solar system. The planet, dubbed Planet Nine, is believed to exist beyond Neptune in the Kuiper Belt. Researchers have noticed unusual gravitational effects on distant objects in this region, which may be influenced by the presence of a large, unseen planet. While it has not b...

  6 Planets Found In Synchronized Orbit May Help Solve Cosmic Puzzle

  They are the most common type of planet observed in our Milky Way galaxy - two to three times the diameter of Earth but smaller than Neptune, and orbiting closer to their stars than our solar system's innermost planet Mercury does to the sun.

  Neptune's Tiny New Moon, Could Be Fragment Of It's Larger Moon Proteus

  A diminutive nugget of a moon has been discovered lurking in the inner orbit of Neptune. The moon, dubbed Hippocamp for the half-horse, half-fish sea monster from Greek legend, is about the size of Chicago and so faint only the powerful Hubble Space Telescope can spot it.

  Discovery of Exoplanet Sheds Light on Planet Formation

  The exoplanet's existence suggests that planets can quickly finalise their orbital distances after forming.

• Astronomer finds new moon orbiting Neptune

  An astronomer studying archived images of Neptune taken by the Hubble Space Telescope has found a 14th moon orbiting the planet, NASA said on Monday.
