A cratered desert world with a thin carbon dioxide atmosphere. Both heavily cratered combined with extensive surface modification from volcanism and other forms of geological activity. Evidence of a tectonic fault-line is present in the above image.

What would cause two stars to collide? What does it take for a whole planet (as massive as Jupiter) to change trajectory?

The main mechanism that would make two stars collide is gravity. This depends on several factors, some stars may wander through space and end up being attracted by the gravitational field of another star, from there, one star begins to orbit the other. 

But the most common are collisions in clusters of stars, because in a star cluster the stars are very close together, especially in globular clusters. 

Collisions of young stars may also occur, as most of the stars are born close to each other in clusters. Many stars are binary, formed together, but in some cases before they evolve they may end up colliding.

In the universe both collisions of active stars can occur, as can collisions of white dwarfs, neutron stars and black holes.

The orbits of the planets are determined by the gravitational pull of the Sun, so it would need some very extreme force to cause the orbit of a planet to change its trajectory, perhaps if some planet or star enters our solar system, or when the Sun goes through changes and become a white dwarf in about 5 billion years.

Hot sun rising over arid wastelands. This planet orbits close enough to the sun to reach 230 F at midday. At sunrise the temperature is already 115 F.

Hey Tumblr!

I have started a new blog to share the joys of fishing and kayaking! This post is all about the best cheap kayaks for under 200 dollars. I hope some of you who are interested can find more about kayaking and fishing! Either way, it’s worth a read if you have a minute. It might just save you a few hundred dollars down the road.
