Just like both Pluto and Earth are rocky bodies but not both called planet. In that case, what is Jupiter? If the planets are only rocky bodies?

This red Tesla, which is circling somewhere around our solar system, is also a body with mass. Sun is also body with mass, can I call it planet? And I did not write about two different people, only about one person, so what you wrote should refer to single planet, for example, only to the moon.

If you leave the bus you change from passenger to pedestrian just like pluto's designation would be different if it were to orbit the sun differently.

Green Baron Posted October 4, 2018 Share Posted October 4, 2018 (edited) Silly Musk's Tesla is an artificial satellite of the sun. It is of course not a planet since it does not even fulfill one of the three requirements. This is silly. Its orbit isn't even stable, it will come close to earth and moon periodically and has a good chance of impacting one of these in the coming millions years. Read the IAU's definitions, they are published together with all the whys and hows you need because these guys are aware. And with that, i am out.

But this is the same planet, the same size, you can find the same raw materials there, no matter where its orbit runs. Body with mass is too broad a term, because the sun or asteroid also have mass, but you will not call them planets. Your categorization failed Now you see that your understanding of my example with a passenger and a human is wrong? Those definitions are nonsense :-) Link to comment Share on other sites More sharing options...
kerbiloid Posted October 4, 2018 Share Posted October 4, 2018 Spoiler If launch a whole bus as a planet, the passengers will become its moons. Link to comment Share on other sites More sharing options...
Snark Posted October 4, 2018 Share Posted October 4, 2018 Some content has been removed from this thread. Folks, just a friendly reminder: We're all friends here, having a civil debate about astronomy. Kindly keep things civil, and refrain from insults and personal attacks. You all already know this, but please leave politics out of the forum. If you want to discuss astronomy on the merits-- including your opinion of whether Pluto should be called a "planet" or not, etc.-- that's perfectly fine. What's not okay is to try to turn it into a political debate. Thank you for your understanding. Link to comment Share on other sites More sharing options...
Deddly Posted October 4, 2018 Share Posted October 4, 2018 This is also a duplicate of another thread linked above, so this one can be closed. Also... Nibiru? Let's try not to introduce pseudoscience and conspiracy theories to our forum, OK? Link to comment Share on other sites More sharing options...
