In the early days of a solar system planetoids can collide with each other on a regular basis, but after the formation of regular planets with orbits, it would be hard to imagine a planetary collision. There would have to be a significantly influential gravitational force, perhaps from a passing star, to alter the orbit of a planet to set it on a collision course with another. We've seen examples of this with exoplanets, where one world's orbit was altered so much as to be made to orbit in the opposite direction of it's star's rotation.
No-one knows for certain
It means between planets, or from one planet to another.
The evening star is another name for the planet Venus. Venus is often visible in the evening sky and is one of the brightest objects in the night sky, earning it the nickname "evening star."
Phobos is considered the most interesting moon of Mars due to its irregular shape and proximity to the planet. It is also one of the smallest moons in the solar system. Additionally, Phobos is gradually moving closer to Mars and it is predicted that it will eventually either break apart or collide with the planet.
Currently, scientists do not have the technology or capability to create another planet. Creating a whole new planet would involve vast resources, advanced technology, and knowledge beyond our current capabilities. While scientists can study planets, they cannot create one from scratch.
It is possible for Earth and a star to collide with one another. However, the possibility is extremely remote.
The likelihood of a moon from another planet colliding with Earth or another planet is extremely low due to the vast distances between celestial bodies. However, in the very distant future, gravitational interactions or orbital disturbances could potentially lead to such an event, but this is highly improbable.
No, Neptune and Uranus will never collide. Their orbits do not come anywhere near one another.
they affect one another's motion only when they collide.
That is conduction.
They collide with one another and tend to spread out randomly.
