Kameahele during periastron, at a distance of 3.8 AUĭue to close encounter with Kameahele, Uranus fell into a more eccentric orbit Kameahele will move away from the solar system and back into interstellar space, roughly towards the constellation Cetus. This would strip away some of the moons of Uranus and would slow down Uranus pushing it into a closer, more eccentric orbit. Upon researching Kameahele's trajectory, they found that the planet will fly past Uranus at an extremely close distance of 95.4 million km. It will appear 4x brighter than Jupiter, and would be so close that it would be visible to the naked eye with no telescope required. Astronomers calculated that the planet will reach periastron (closest point to the Sun) on October 21st, 2269, at a distance of 3.8 AU, and would also appear in the constellation Ursa Major as viewed from Earth. The planet, dubbed "Kameahele" meaning "wanderer", appeared to be coming from the constellation Scorpius, more specifically the star V1003 Sco, at roughly 17.2 km/s. This marks an incredible discovery in astronomy, as it is the first known planetary-sized interstellar object to pass through the solar system, and the second known interstellar object to pass through since Oumuamua back in 2017. Upon researching, they found a bone-chilling discovery.Ī massive planet, over six and a half times more massive than Jupiter and nearly 2.3 times its diameter, is found to be moving at an incredible high speed directly into the inner solar system. While the bombardment is not as intense as the Late Heavy Bombardment, astronomers are sure that there is something in the outer reaches of the solar system that is responsible for this event. The year is 2123, a large swarm of comets enters the inner solar system, with several close encounters with Earth, and some others hitting planets like Jupiter and Mars. As far as strange things go I'm not going to be betting against the universe coming up with anything short of impossible, and what we now think of as impossible may prove to merely improbable, or possibly even more common place than we'd ever imagine. Until we started discovering exoplanets we thought it would be impossible for a jovian sized planet to be in close orbit to a star. Some planets survive to be ejected from the system, or into a long trip round to come back to the center for another death defying encounter.Īll that said, what we think is impossible today has often proved wrong tomorrow. What's really telling is that if you take that system and use the Tool: Auto-Orbit all the nice round orbits go to hell with everything heading straight for the black hole/star center. That still doesn't make the system I posted anything more than a fun simulation. According to that theory the smaller the black hole the faster it will evaporate. He also believes that black holes will evaporate over time due to what has become known as Hawking radiation. Still only a theory, but Stephen Hawking himself came up with the idea of micro black holes. Now, I doubt very much that such a system exists, but it's a fun simulation none the less.ĭid a bit of research on how small a black hole could be. Due to the effects of it's orbit around both a star and a black hole it's surface temperature varies from a high around 40 C, and a low just below 0 C as it travels from outer portion of the green habitable zone dipping into the red part of the zone at it's closest point to the black hole/star combo. Within the habitable zone, well, it's there most of the time, I placed a 1.4 Earth mass planet with a viable atmosphere and material composition to support life. I then lowered it's mass to 272 Jupiters and placed a 107 Jupiter star in close orbit, followed by a planetary system. Can't say that I've read all the posts here, but someone else must have tried something like this: I started with a small 1 M Sun Black Hole, set it to locked so the system wouldn't take off on me.
