What if there were two Earths in the solar system?

The prospect of two planets sharing the same orbit is possible, but it wouldn’t last forever. Another possibility is a binary planet system, in which two Earths of comparable size could have separate orbits, with one orbiting outside of the other. Think of the Moon, the Earth, and the Sun.

Is there two Earths in the solar system?

Two Earth-size planets have been discovered in a neighboring solar system. They’re located in the “habitable zone,” where liquid water could exist on a planet’s surface. That means potentially habitable planets would have to be closer to it than those in our own solar system, and thus orbit more quickly.

Can two Earths orbit each other?

Actually… the answer is theoretically yes. Two Earth-size planets that orbit each other might exist around distant stars. Binary stars, or two stars orbiting each other, are very common throughout our own galaxy.

Could there be another Earth on the other side of the Sun?

No. Just no. This is a delightful staple in science fiction. There’s a mysterious world that orbits the Sun exactly the same distance as Earth, but it’s directly across the Solar System from us; always hidden by the Sun.

Could a counter Earth exist?

Nonetheless, a Counter-Earth could still be detected from the Earth for a number of reasons. Even if the Sun blocked its view from Earth, a Counter-Earth would have gravitational influence (perturbation) upon the other planets, comets and man-made probes of the Solar System.

Is there a second Earth in our Solar System?

Earth 2.0 is positioned within a habitable zone relative to it’s star, meaning it’s not too hot and not too cold, and it’s likely to have a rocky surface too. While this planet could plausibly be a cousin to Earth, it’s about 1,400 light-years away from our Solar System… But suppose we had a second Earth in our Solar System.

What would happen if two planets share the same orbit?

The prospect of two planets sharing the same orbit is possible, but it wouldn’t last forever. Eventually, the gravitational interaction between both planets would either cause the two of them to collide; or one would end up pushing the other one towards the Sun, and we’d be back to just one Earth.

Where in the Solar System can we fit another Earth?

If we’re going to fit another Earth anywhere in our Solar System, our best bet is somewhere between our planet and Mars. Our Earth is on the inner edge of the Solar System’s habitable zone, and with Mars closer to the outer edge, anything past it might be a little too cold for a species like ours.
