Does this planet have a “sibling” sharing the same orbit? | ESOcast Light

Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have found the possible ‘sibling’ of a planet orbiting a distant star. This video summarises the discovery.

This would be amazing to see.

[@LouseGrouse]

This is a really great find

These video's say ESOcast light, so are there longer versions somewhere?

[@ESOobservatory]

We used to produce longer videos with a host or voiceover, called ESOCast, dealing with a variety of topics. The ESOCast Light videos aren’t shorter versions of those videos, just different videos that happen to be shorter, normally focused on recent discoveries. For more information about these discoveries you can check the link to the corresponding press release that we include in the description of the video. The longer hosted video format has been revamped into a new series called Chasing Starlight, which you can watch here: kzbin.info/aero/PLSZ2Jv0bEZHybSxOQdx-tY96Qx2-lAHAN

It wouldn't be a regular planet then. Just like Pluto, these two objects would be dwarf planets.

[@bladrbrettel6511]

I think it will depend on the diameter of of thos planets the diameter of Pluto is 1000km or about 700 miles less than the moon... I would add Theia was the sibbling planet of Earth... In the shirt video here they did not tell how old is this system ! May be in a few million years those planets will do like Earth and Theia ! Should be Great to see that 😋

So this is a solar system still in formation? How many light years away is it?

[@ESOobservatory]

Located nearly 400 light-years away from Earth, PDS 70 is indeed a young planetary system in the process of forming. In particular, the ring-like structure that dominates the image is a circumstellar disc of material, out of which new planets are emerging.

@@ESOobservatory How amazing and so close really! What an incredible chance to view it over the decades to come.

[@KCTattooist101]

Point of our perspective it only looks like it shares orbit.

Esta dupla descoberta escrutinada pelo fabuloso ALMA guiada por uma brilhantissima estrela e dois planetas a partilhar a mesma órbita!! Serão gémeos falsos, como serão constituídos?! O Universo continua a espantar-nos pela sua criatividade!!

[@ESOobservatory]

Yes, the Universe never fails to amaze us with its infinite surprises, and this recent discovery is undeniably thrilling! However, it is still uncertain whether this cloud of debris will lead to the birth of a new planet, or if the cloud is the leftover of an already-formed one. And even if in the end a planet will form, it is highly probable that it would not be an identical twin to PDS 70b, but rather a simple "sibling". Why? Because on one hand, by following the same orbit, they would share the same duration of the year and receive a similar amount of energy from the central star. But on the other hand, they would be quite different in mass, size and composition. This would be due to the fact that, while PDS 70b is a Jupiter-like gas giant, the cloud of debris has an estimated total mass of up to approximately twice that of our Moon.

Obrigada ESO pela disponibilidade e pela extraordinária explicação de todos os pormenores desta incrível descoberta!! Grata por tudo...e pelo conhecimento que me trouxeram!!
