There may be a giant planet hiding in our solar system beyond Neptune. Scientists have found evidence of a massive object that could be influencing the orbits of other distant objects. If confirmed, this would be the ninth planet in our solar system and the first one discovered since Pluto was demoted in 2006.

When I was a kid, Pluto was planet nine. *sniff*

WRITER FUEL: The elusive "Planet Nine," which may or may not lurk in the outer reaches of the solar system, could be surrounded by a small swarm of potential moons, a new study reveals. What's more, these moons could be the key to finding the missing planet.

I wonder if #PlanetNine will be discovered (again—I still remember you #Pluto!) in our lifetime‽

The #math says it’s there (just like it confirmed #Neptune’s existence), but I still wonder if it could be a brown dwarf instead.

We could also have a tiny #BlackHole orbiting our solar system (which would be awesome & scary).

A Giant Planet Seems to Be Lurking Somewhere in Our Solar System

I am not knowledgeable about the James Webb Space Telescope (JWST) but if it can see stuff so far away why can't it see Planet Nine?

@mustapipa
Vaikka menee ohi tämän tuuttauksesi aiheesta, kysyn kuitenkin että millaisia ajatuksia sinulla on hypoteettisesta yhdeksännestä planeetasta? Mahtaako se olla siellä?

Mysteries of Our Outer #SolarSystem - The coldest, darkest reaches of our Solar System – a region still to be visited by human #spacecraft – is a strange, frigid cloud that contains material from other #stars and an unconfirmed object known as #PlanetNine that may actually be a planet-mass #blackhole.

#Planetnine https://youtu.be/Qwz7Z5cUDuM question to the Mastodon #astronomer community : Given the number of #telescopes 🔭 https://en.wikipedia.org/wiki/List_of_space_telescopes (including #JWST), how does it come we may find 5,284 #exoplanets up to 27,710 #lightyears away https://en.wikipedia.org/wiki/List_of_exoplanet_extremes#Extremes_from_Earth's_viewpoint but not #planetnine in our own #SolarSystem ? https://en.wikipedia.org/wiki/Planet_Nine#Visibility_and_location

Is this comparable to the search for #asteroids https://techhub.social/@spaceflight/109539548812565245 (which are way smaller) ?

A long read. Story by Shannon Stirone. In her words: "Last month I went to Hawaii with Mike Brown and Konstantin Batygin to search for Planet Nine. This is the story of what happened at the telescope, and the challenges that come with discovery."
