What mind you expect to find if you were to come back to our solar system in 1 billion year?
The Sun would be largely unchanged, though it would be only four billion years from its red giant stage.
If humanity managed to avoid killing itself and explored space, the planet Mercury would probably be gone as we would have mined it into nonexistence.
Venus might have been terraformed and would then be enjoying some primitive life.
Earth? Hard to say. We might have polluted it back to an azoic condition or left it altogether.
Earth's Moon would be much farther away. No more solar eclipses visible from the planet.
Mars would be pretty much as it is today; even if we managed to terraform it, its low mass would have let its atmosphere escape again.
Jupiter might have moved in closer to the Sun.
Saturn's rings would be gone.
The Ice worlds would be unchanged.
Of course, Nemesis/Shiva, the Sun's putative dwarf companion, might have made about forty passes, any one of which could have provoked a catastrophe.
We would in all probability have drifted out of the Origin Spur and into a region of either more or less interstellar matter.
All the constellations would be changed beyond recognition and all the bright stars of the Earth's sky would be burned out.
Well, here's the thing: comets have crazy, irregular orbits. Because of this, they're likely relics leftover from when the solar system formed. So they probably haven't changed much in the last 4 billion years or so. If we anayze what they're made of, it can give us a clue to the composition of matter back when the solar system first formed, which can give us clues about how things have changed since then, and how…
The solar system as the beginning is estimated by the determination of the age of the Sun when it ignited as a star. This is evidenced to be about 5 billion years old, and has about another 5 billion years of hydrogen (using 400 million tons every second) left to change into helium which is the process by which the Sun is powered by its thermonuclear fire. The earth and the other planets appear to…
Galaxy A galaxy is made up of millions and millions of stars, therefor, could not be withing a single solar system. Astronomy is a subdivision of science which means that all the fact that are in science are in astronomy. This means that a tiny particle in the solar system would revert back to chemistry where you learn about sub-particles. I.e. electrons, neutrons, and protons. It would be the same question with out adding "in…
The solar system condensed out of a cloud of interstellar gas, some four and a half billion years ago. The gas was rotating, and that angular momentum became the various forms of revolution and rotation found in the planets and the sun. Ultimately, if our current understanding of cosmology is correct, the rotation of the original gas cloud can be traced back to the Big Bang. It derives from the original expansion of the universe.
I THINK either everything will die or all the planets will be pushed into another solar system This is just my predicition JUST OPINIONS _______________________________________ Actually, the entire solar system will be obliterated. What happens is, the sun will start to go into the red giant stage and will start expanding outward. It starts to engulf the solar system and so on and so forth. So then, it starts shrinking back to normal and becomes…
Radioisotope dating of moon rocks showed that the age of the oldest lunar rock was closest to how many years old?
Rocks from the moon have been dated to about 4.5 billion years old. The oldest earth rocks don't date that far back because the earth "reprocesses" rock, and the oldest rocks we know of on earth date back to about 3.7 to 3.8 billion years. The earth and moon formed at approximately the same time, as did the rest of the solar system.
