Extinction-1

Extinction-1
Extinction's 4 planets will soon be 1. A black hole is currently hurtling through the void at an inclination of 19. Within months, it will slingshot around Extinction d, causing it to stretch outward and be consumed in the process. It will pass at an angle around the Star, then will directly hit Extinction b. This will destroy the planet, but will also probably shoot out many asteroids. Then it will pass very close to Extinction c, giving it a large chance of destruction. However, depending on the momentum, it could simply pull on the planet then rapidly stop, causing the 'earth tide' to slosh back onto the planet, possibly creating a new ring system and/or a moon.

Star-
The Star is a K4-5. It is expected to see some oblateness as the black hole passes by, which may cause 'aging' of the now 1 1/2 billion year old star, or in extreme cases, destroy the convection process, drastically shortening the lifetime of about 65 billion to 7-8 billion. However, the latter is unlikely.
