| yesterday | comment | added | JBH | @eys Alex may correct me, but to achieve that goal would require a hotter star with a much lower mass than our sun (e.g. white dwarf/blue subdwarf). If a star like our sun came close enough to remarkably change our climate it would screw up the whole solar system (including the orbit of our sun). Also keep in mind that while a plausibly low mass star could be had, it's uncommon (but not unknown) for the star to not be orbiting the galactic core. But a small companion star ejected by a primary star nova would explain your event. Your world would see it coming.... | |
| yesterday | comment | added | eys | @AlexP Could a star hotter than our sun approach close enough to affect a planet’s climate and then go further away again without completely throwing the planet off its orbit? Im wondering if in the perfect circumstances something like this could happen or is it a definite no. | |

| yesterday | comment | added | AlexP | The Sun definitely has an overwhelming gravitational influence over Neptune, but as seen from Neptune the Sun appears as a very bright star (magnitude -19.3, about 500 times as bright as the full Moon seen from Earth) with minimal influence over the environmental conditions. Yes, it does provide some light, about as much light as we have here on Earth in winter on a heavily overcast day; no, it does not provide any noticeable amount of energy. For example, our space probes can rely on solar panels for their electric power only to about the orbit of Jupiter. | |

| yesterday | comment | added | eys | @AlexP couldn’t a second sun in the sky effect a planets climate without having an overwhelming gravitational influence if it’s at a certain distance | |
