5 Earth masses? On an astronomical scale, such a black hole would be short lived. Using Hawking’s theories on the evaporation of black holes, the lifespan of a black hole is proportional to its mass raised to the fourth power.
1.25 * 10^50 seconds, or 3.96 * 10^42 years. Not what I would consider a “short time”. Plus, the lifespan of a black hole is proportional to its mass raised to the third power.
