Will adding a planet to our solar system make Earth's orbit unstable and cause it to fall into the Sun?

It is unlikely that adding a planet to our solar system would make Earth's orbit unstable and cause it to fall into the Sun. The planets in our solar system are all in relatively stable orbits, and it would take a very large and/or close planet to significantly perturb Earth's orbit.

However, it is possible that adding a planet to our solar system could have some other effects on Earth. For example, the new planet could alter the Earth's climate, or it could cause more asteroid impacts.

The exact effects of adding a planet to our solar system would depend on the mass, orbit, and composition of the new planet. However, it is unlikely that the new planet would cause Earth's orbit to become unstable and cause Earth to fall into the Sun.

Here are some additional factors that would affect the stability of Earth's orbit if a new planet were added to our solar system:

• The mass of the new planet: A more massive planet would have a greater gravitational pull on Earth, which could make Earth's orbit more unstable.
• The orbit of the new planet: A planet that orbits close to Earth would have a greater gravitational pull on Earth, which could make Earth's orbit more unstable.
• The composition of the new planet: A planet that is made of gas or ice would have a lower density than a planet that is made of rock, which would make it less likely to perturb Earth's orbit.

Overall, the stability of Earth's orbit would depend on a number of factors, including the mass, orbit, and composition of the new planet. However, it is unlikely that adding a planet to our solar system would cause Earth's orbit to become unstable and cause Earth to fall into the Sun.
