  How do Sedna and that new one have a stable orbit? Are they that fast, to be able to compensate the movement of Pluto?

  Obviously there’s a Planet X out there, whereas would Chemical X come from

  So, draft planet 8.1 ? 8.3 because of Pluto and Charron?

  They prefer to be called little planets, tyvm.

  But I am not sure how to process this as a planet X fan

  When we hit the floor you just watch them move aside
  We will take them for a ride of rides
  They all love your miniature ways
  You know what they say about small boys

  “The object is currently about 90.5 astronomical units (AU) away from us, or roughly 90 times as far from Earth as the sun is.”

  This sentence pissed me off so much and I stopped reading after it.

  It is 90.5 times as far from the Sun as the Earth is from the Sun. Why’d you have to go and change the frame of reference to Earth?

    They didn’t change the reference, they defined an AU.

  • Kichae@lemmy.ca ⁨10⁩ ⁨months⁩ ago

    It didn’t. It’s 90.5 AU from us, and us is Earth. Or do you live on the Sun?

    • tiny_hedgehog@lemm.ee ⁨10⁩ ⁨months⁩ ago

      If we are 1AU from the sun, and this planet is 90AU from the sun, then it is between 89 and 91 AUs from earth depending on the progress of our orbits (assuming perfectly circular orbits). So they did change the frame of reference.

    Well it’s a good frame of reference because it’s where most of us keep all our stuff.

    I mean, they said “roughly”.

      Like, give or take one AU, throughout the year.

  Ugh, didn’t read the “dwarf” part and got my hopes up for planet 9. When they eventually do find it they have to name it something with P so that the old mnemonics still work.

    This study authors btw say that their models for 2017 OF201’s orbit work best without the influence of a hypothetical planet 9

    “Planet 9” starts with “P”

  This far-flung orbit may be the result of an encounter with a giant planet, which ejected the candidate dwarf planet out of the solar system, say the researchers.

  Poor guy. Hopefully he’s out there finding his own family.

  At least it doesn’t have to deal with the toxicity Pluto does, being in the family one day and then coldly rejected from the family from the planet club the next. And we wonder why it’s exterior is frozen…
