What if this massive alien planet trespassed the borders of our Solar System? If that rogue planet have sufficient velocity and under perfect conditions (such as the angle of collision), yes there is a possibility that it could reach the sun (bringing along with the 'planet' it collided say Pluto). The only way we could survive would be if we learned to live at the bottom of the ocean, next to deep-sea thermal vents that push out extremely hot water.

Could Earth Be Hit, Like Jupiter Just Was? What are the chances of a rogue planet hitting us? Finding rogue planets is extremely challenging because, unlike stars, planets do not emit light of their own. The short answer is no. If a planet doesn’t belong to any star system, it’s considered a rogue planet. So even an “invisible” rogue planet could act as a gravitational lens – or micro-lens, as they can be so small. Earth is tiny as planets go so a rogue of average sizes gravitational field would cause massive tidal waves around the world maybe even cause the tectonic plates to shift causing massive world wide earth quakes.

And now an Earth-sized rogue planet has been identified by researchers. Planets get ejected from their original solar systems for different reasons. Scientists think these planets might adopt distant orbits as much as 1,000 times farther from a star than Earth is from our sun. Unlike Earth, which is orbiting the Sun, there are billions of rogue planets roaming the Milky Way not bound to any host star. I keep having really really scary dreams about a rogue planet hitting earth and it feels so real and i'm scared out of my mind to dream about it and i keep crying because for some reason i feel like a rogue planet will hit earth in my lifetime and i'm only 16 so my question is that if a rouge planet was on a collision course what can we do to stop it from hitting earth? And so would we. Like a rogue planet, rogue stars are also found in the universe.

If we were unlucky enough to be on a collision course with this massive alien object, the Earth would be completely demolished. That’s because a rogue planet nearly 13 times bigger than Jupiter would have a huge gravitational impact, making other planet’s orbits, including Earth’s, more elliptical. Nearby rogue planet candidates include WISE 0855−0714 at a distance of 7.27 ± 0.13 light-years. 9 min read. Could rogue planets support life? This planet is currently being pulled by the gravitational force at our galactic center, but if it came close enough to our sun it could be sucked into its gravitational pull. By the end of our first never-ending winter, humanity could face food shortages, even extinction. Let’s find out. As of 4.5 billion years ago, Earth has been in a stable orbit around our local star; the Sun. “If the lens were orbiting a star, we would detect its presence in the light curve of the event,” adds Dr. Poleski. The ejection phenomenon of the rogue stars … Comets and asteroids hit the sun quite regularly, with little evidence remaining of their prior existence. Could a planet ever collide with Earth?

There’s a lot of space between rogue planets and other objects in our galaxy. Could a rogue planet create a 100m tide on earth without catastrophically affecting it's orbit? But what is a rogue or nomad planet, and why should we not be afraid of something that big hurtling through space? About 4.5 billion years ago, a small planet crashed into a larger planet in the Solar System - forming Earth … Wow, right? But the bigger question is …. The rogue planet might not push us out of the habitable zone, but it would bring us much closer to the Sun for very short and exceptionally hot summers. So even an "invisible" rogue planet could act as a gravitational lens—or micro-lens, as they can be so small. All of our water would freeze. By Charles Q. Choi 28 July 2009. Let’s just say that scientists aren’t worried about it, so you shouldn’t be either. If the earth were flung out of the solar system, it would rapidly become far too cold for any unprotected life to survive on the surface. best.

Bengaluru: Astronomers have found a rogue planet, which is about the same mass as Earth, seemingly adrift in the Milky Way, without being a part of any star system.Such planets are called rogue planets, and this new planet is considered to be a low mass planet. It was discovered in 2014 and is approximately 7.2 light-years away from us. Or it may arise from the gravitational collapse of part of an interstellar cloud. Solar energy, on the other hand, would be considered very inefficient in the wintertime but could be used very effectively during the short blaze of summer.

It wouldn't be unprecedented. If another star passes within ~1 Earth-Sun distance from the Earth, then there is a good chance that the Earth would wind up being ejected into interstellar space. (Diego Barucco/Shutterstock) Or instead of just passing by and disrupting Earth's orbit, a drifting world could make a direct hit.
