How many joules of energy would the Death Star's primary weapon have to generate in order to overcome the gravity holding together an earth-sized planet in order to blow that planet apart?

400 Octillion Joules. (400,000,000,000,000,000,000,000,000,000)
It's not really a fair question, however.
The Death Star, as depicted in the Star Wars Movies, is grossly overpowered for its purpose. It would take a tiny fraction of that energy to simply vaporize the surface and wipe out all life.
Okay, I admit I did not actually calculate the energy required to vaporize a planet. I simply assumed that the energy output of a Sun like star would be sufficient if it were all turned on puny little Alderaan (or Earth).
The Sun outputs 400 Octillion Joules / second.

Stars are formed from interstellar clouds because of?
Because of gravity. Only gravity can pull large clouds together with enough force to overcome gas pressure.

Is a nebula held together of the outward force of gravity?
No an nebula is held together by the balance of the inward force of gravity and outward pressure.
What force is responsible for holding the stars gases and dust together in a galaxy?
The answer is simple: gravity.
How do astronauts overcome gravity in space?
In space, there is no gravity to overcome. The chllenge to astronauts is how to deal with the lack of gravity.
How do you beat gravity on Earth?
To overcome gravity, you must reach "Escape Velocity" to overcome gravity and escape a planet's orbit.

Why are magnets able to overcome force of gravity?
You don't specifically need a magnet to overcome the force of gravity; ANY force that is stronger than gravity can "overcome" it, at least temporarily. For example, if you lift an object up, you are "overcoming" the force of gravity.
What does a spacecraft need to overcome?
it needs to overcome the gravity of the earth lol
How you overcome gravity?
Go to space.

Gravity
How does a trampoline work?
Applied physics! The jumper uses muscles to generate energy. This energy is used to overcome gravity, and the when gravity returns the jumper to the tramp, the tramp "catches" the jumper. In catching the jumper, the tramp stores the jumper's energy in its springs, and then returns it to the jumper. Simple and easy.
What did the Wright Brother's overcome?
