Плутон снова может стать планетой

Причина, по которой Плутон потерял свой статус планеты, недействительна, согласно новому исследованию от Университета Центральной Флориды в Орландо. В 2006 году Международный астрономический союз, группа мировых экспертов в области астрономии, установила определение планеты, по которому она должна «расчищать» свою орбиту или, другими словами, иметь самую большую гравитационную силу на своей орбите.

Плутон снова может стать планетой

Поскольку гравитация Нептуна влияет на соседнюю планету Плутон, а Плутон делит свою орбиту с ледяными объектами пояса Койпера, статуса планеты Плутон лишили. Однако в новом исследовании, опубликованном в журнале Icarus, планетолог Филип Метцгер сообщил, что этот стандарт классификации планет не поддерживается исследовательской литературой.

Почему Плутон не планета?

Метцгер пересмотрел научную литературу за последние 200 лет и нашел только одну публикацию — от 1802 года — которая использует аргумент очищения орбиты для классификации планеты, основанный на опровергнутых уже рассуждениях.

Он говорит, что спутники, такие как Титан и Европа, считались планетами со времен Галилея.

«По определению МАС фундаментальный объект планетарной науки, планета, определяется на основании концепции, которую никто не использует в своих исследованиях», говорит Метцгер. «И лишает этого статуса вторую по сложности, самую интересную планету нашей Солнечной системы. У нас есть список из более сотни недавних примеров, когда планетологи использовали слово «планета» в нарушение дефиниции МАС, но делали это, потому что это было функционально полезно. Дефиниция МАС небрежная. Она не объясняет, что значит расчищать свою орбиту. Если принять это буквально, не существует планет, потому что ни одна планета не расчищает свою орбиту».

    Hi there this is somewhat of off topic but I was wanting to know if blogs use WYSIWYG editors or if you have to manually code with HTML. I’m starting a blog soon but have no coding know-how so I wanted to get advice from someone with experience. Any help would be enormously appreciated!

  12. My husband and i felt now joyful Ervin could finish up his inquiry with the precious recommendations he was given in your web pages. It’s not at all simplistic just to happen to be making a gift of methods that many people may have been trying to sell. Therefore we understand we need the writer to give thanks to for that. These explanations you made, the easy website menu, the relationships you will make it possible to foster — it’s got all astounding, and it’s really leading our son and the family consider that that subject matter is thrilling, and that is extremely serious. Thanks for all the pieces!
