imagine space-time, as a series of cubes, all uniform size and shape, perfectly symmetrical.
now imagine an object of high mass is placed into this field of cubes, and squished them around it to the shape of its gravitational field, compressing space-time around it.
the larger the body, the greater this effect.
in the case of a singularity and it's event horizon, close proximity to such would create a hugely compressed zone in space-time, this increases the space traveled for a set linear distance when passing through the compressed region.
it also increases the time traveled in a linear distance-time relationship.
that is what happens on the surface of the planet in your picture, that space-time field is condensed to the point of a 525,600 multiplier (525,600 minutes in a year, where one minute on target planet is the same outside of the compressed space-time field as 1 year in normal space-time)
