Jupiter may just assimilate it, or it may toss it toward the Sun.
Neptune would pass a protoplanet to Uranus, which would pass it to Saturn, which would pass it to Jupiter.Inevitably, the larger masses would start interfering with the orbits of the slightly smaller masses, and the combined gravitational/rotational interactions would have the effect of flinging the smaller ones either out to the margins of the planetary system or in toward the central star. They'd start pulling greater and greater quantities of volatiles and liquids into themselves.They would grow and their gravitational attraction would increase rapidly. All volatile and liquid elements that would be given off by an early star would gather quickly into frozen blobs in the cold outer reaches of the system.Formed within the first 10 million years of development of a star-planet system or they didn't ever develop.If you could live forever, would you?

Meanwhile, there is this one:Īn asteroid lingers near Earth and devours time (13:23 min) Or, at any rate, it devours our perception of time, as one man discovers in “Flyby.” As the asteroid Chrono-7 hazes Earth, a man wakes up in the morning to find that he is living in his future, one he had never imagined.
Maybe the possibility of an asteroid hit will generate more post-asteroid apocalypse sci-fi. An asteroid hit is believed to have wiped out the dinosaurs and many other types of life forms 66 million years ago.
NASA has catalogued 26,000 near-Earth asteroids so far. Meghan Bartels, “ Scientists fine-tune odds of asteroid Bennu hitting Earth through 2300 with NASA probe’s help” at (August 11, 2021)Ī paper discussing the Osiris Rex’s findings is open access. How precisely that dance plays out will shape Bennu’s trajectory over the next decades and centuries. In September of that year, Bennu will swing past Earth - not close enough that there’s any risk of an impact, but certainly close enough that Earth’s gravity could nudge the asteroid a bit on its path. However, despite the scientists’ best efforts, predicting Bennu’s course after 2135 is still tricky. That uncertainty remains even in the new and improved models of Bennu’s future path, but with the OSIRIS-REx observations, scientists were able to dramatically reduce their uncertainty about Bennu’s fate… Scientists’ models of asteroid trajectories always include some degree of uncertainty, since a multitude of forces tug at a space rock as it rattles around the inner solar system.
