What would happen if another planet enters our solar system?

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. Those extreme summers would be followed by long and super cold winters. Quick summers would leave us less time to grow crops.

What would happen if all 8 planets lined up?

The closest that the eight planets will come to being aligned (Pluto is now considered a dwarf planet) will occur on May 6, 2492. Again, on this date, the planets will not be situated along a line….When do the planets in our solar system all line up?

Astronomical Body	Gravitational Force (N)
Earth	980
Sun when closest	0.61
Sun when farthest	0.57
Moon when closest	0.0039

What would happen if Earth went rogue?

If earth became a rogue planet, its temperature would start decreasing as it moved further away from the sun, so we would need more energy to heat up. Find a way to produce oxygen.

How does the gravitational pull of other planets affect the Earth?

The gravitational pull of the other planets in the solar system affect the Earth’s orbit in several ways. Jupiter in particular has an effect on other planets including Earth. Most moons in the solar system are small in comparison with the planet they orbit around. The Moon however is quite large relative the the Earth.

What would happen if all the planets in our solar system disappeared?

Only the bigger planets’ disappearance would cause changes over a period of time; namely, there would be a change in how some planets interact with each other. We think of our Solar System as a big family of celestial objects that interact with each other in various ways.

What is the final planet in the Solar System?

Neptune: Neptune is the final planet in our solar system. Beyond Neptune lies the Kuiper Belt, an asteroid belt, and many dwarf planets, including Pluto. Neptune dominantly controls the orbits and movements of objects in the Kuiper Belt with its gravity, as the Sun’s gravity is considerably less in these far extremes of the Solar System.

What would happen if Saturn suddenly disappeared?

Saturn’s disappearance would affect the orbits of Jupiter and Uranus by some degree, due to its sheer size and mass. However, given its distance from the inner ring of planets, it’s tough to imagine that Saturn would have a similar impact on the smaller inner planets.
