Scientific curiosity, In search of planet 9. - My Actifit Report Card: October 3 2024

They have undertaken the search for planet 9 because we know that there are objects beyond Pluto, dwarf planets, asteroids or giant comets, more and more objects are being discovered, what happens is that many of them have an anomalous orbit, which does not correspond to which would be normal within the calculations of the orbits of the solar system, therefore, for some time now the theory has emerged that something has had to alter the orbits of these objects and one of the explanations would be the existence of a planet, That's why they call it planet nine. There are several versions, one says that it would have a mass like one, three or four earths, another a little larger, there are several versions of what it could be like; Another explanation would be that it was a primordial black hole with a mass similar to that of a planet, four Earth masses or more; Another theory would be that it was actually due to the passage of a star near the solar system, which would have caused these deformations in the orbits of those objects, but they are there, and they are looking for evidence to prove which theory is right.

The planetary solar system is 4 light hours to Neptune, but in the solar system, how far does the sun's gravity go, how far the last Comet is orbiting the sun, some say it can be up to a light year, that is 365 light days, that is, the Planetary solar system would be less than one radio light day, but the entire solar system could be about 365 radio light days, that is, it is much larger, which is why it is easier for a star to pass through there than to cross the inner solar system. .
