In theory, the death of a star would be the cause of the death of a planet, making both catastrophic events. The death of a planet can range from the destruction of the vegetation to the destruction of the planet itself. Either way, if something makes the planet uninhabitable, then it is considered dead. The death of a star is quite different. A star doesn't have an ecosystem or anything like that. However, if a star were to go super nova, it could wipe out several planets as well, thus making them into dead planets. A star could also just fizzle out, which could cause the death of planet(s) that use the star for heat, like our sun. If our sun were to go out, our planet would become dead. I hope this is what you were asking for, and sorry if it's not. My source of information is my knowledge gained from watching Star Wars, Star Trek, Doctor Who, and the Sarah Jane Adventures. :-)
Stars give off light whereas planets reflect light.
Planets are not stars, and there's no such thing as "death stars".
A planets and stars are different things, so a planet can never be a death star.
A galaxy contains planets and a star system contains only stars.
Ancients distinguished between planets and stars in the night sky by observing that planets move relative to the fixed background of stars, while stars maintain their positions.
Planets orbit stars, moons orbit planets. That is the only difference.
Planets do not naturally generate nuclear fusion. Nuclear fusion occurs in stars, where the extreme heat and pressure at the core allows hydrogen nuclei to merge and form helium, releasing energy in the process. Planets lack the conditions necessary for sustained nuclear fusion reactions.
Astronomers study the stars, the planets and the known universe.Astrologers study horoscopes (a geocentric map of the heavens at the exact time, place and date of birth or an event) to divulge the influence of the planets and stars on a given person, place or thing.
Galaxies are formed by stars, planets, comets, meteors, and other space bodies.Stars have their own source of energy, tones of hydrogen burned into hellyum every second, while planets don't have, and get heat from the nearest star. Stars are the furnace of the universe eventually allowing planets to develop life, like the Earth.
the difference is that stars are much bigger in size than a planet
Stars are massive celestial objects primarily composed of hydrogen and helium that generate energy through nuclear fusion. Planets, on the other hand, are smaller celestial bodies that orbit around stars and do not produce their own light. Planets can be rocky, gaseous, or icy, and they do not undergo nuclear fusion like stars do.
Planets orbit stars.
