According to the International Astronomical Union (IAU), there are eight planets in the Solar System: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Meanwhile, Pluto, Ceres and Eris are dwarf planets.
Scientists explain that, first, you have to take into account how planets are formed. A planet is considered to have been formed when the sufficient amount of material that was scattered throughout the space to have a good gravity.
Here's How Far You Can Throw a Ball on Other Planets - Nerdist
Laughing Squid picked up on O’Donoghue’s new planetary sciences video, which is just one of dozens he’s posted to his YouTube channel . Previously, the Japan-based scientist showed us how fast various planets spin compared to one another.
In O’Donoghue’s video (above) he shows how far a ball thrown at a 45° angle would travel on various planets in the solar system. As well as the Moon and Pluto. Notably, O’Donoghue assumes no atmospheric resistance for his calculations and a starting speed of 45 mph for the ball.
Astronomers Make the Case for Calling Pluto a Planet Again - ExtremeTech
Pluto was generally accepted as a planet from the moment it was discovered in 1930, but we didn’t know much about the outer reaches of the solar system at the time.
Is that correct, though? The new study argues that it isn’t, claiming the change was based more on astrology than astronomy. By 2006, we already know about objects like Eris and Makemake which would have fit the old definition of a planet.
This New Trend on Tiktok Has Users Turning Their Friends Into Planets
The latest trend on TikTok is turning pictures of your loved ones and friends into virtual “planets” using a fun new phone wallpaper editing trick.
The new#planetwallpaper trend involves using the third-party app, PicsArt to create swirled images of your favorite pictures on your phone and then transforming the swirls into a galactic spacescape you can use as your lock screen.
The search for rogue planets in outer space - Skywatching - Castanet.net
It is wandering the spaces between the stars and the only light is distant starlight. It is cold, a few degrees above absolute zero: the temperature at which everything stops. Most gases are frozen solid. There could be a thin atmosphere of helium, the gas with the lowest boiling point.
This raises a big question. If planets form along with stars, how can they come to be wandering the galaxy alone?
Flame Nebula: Stunning interstellar clouds captured in new images - CNN
(CNN) The Flame Nebula is one of many gems included in the Orion constellation, and astronomers have now captured a new perspective of this striking celestial feature.
Eccentric exoplanet discovered -- ScienceDaily
Led by the University of Bern, an international research team has discovered a sub-Neptune exoplanet orbiting a red dwarf star. The discovery was also made thanks to observations performed by the SAINT-EX observatory in Mexico.
"Red dwarfs" are small stars and thus much cooler than our Sun. Around stars like these, liquid water is possible on planets much closer to the star than in our solar system.
New year's mission to start new phase of exoplanet research
The ASTEP telescope detects signals from distant planetary systems using the 'transit' method, measuring the slight dips in brightness that occur when a planet passes between Earth and its host star .
Purchased with support from the Science and Technology Facilities Council and from the European Research Council, the telescope's new camera is sensitive to the reddest wavelengths in the spectrum.
Humans will quickly go blind if we travel to other planets, researchers warn - The Bharat Express
Astronauts are increasingly complaining about needing specifications when they return to Earth, experts report.
Scientists looked at neuro-ocular syndrome associated with spaceflight (SANS) and compared brain scans before and after space travel.
They claim that the longer astronauts stay in space, the more they complain of problems with blurred vision and eyesight when they return to Earth.
