Length of the Last Hand: From the wrist to the tip of the longest "finger" is roughly 6,500 light-years. The region itself has a general width of about 3,000 light-years, though this is still under evaluation due to the region's dynamic nature as it spreads further from the galactic core.
The Fingers: The six "fingers" of the Last Hand stretch from 1,000 to 4,000 light-years each. These fingers are the last remnants of the most active and brightest stars of the broken stellar arms. As stars detach, they drift outward, forming long, irregular tendrils that point into intergalactic space.
The Wrist: The wrist faces the direction of the galaxy's former core. It is the central point from which the fingers extend. As space continues to stretch out, the region's gravitational influence weakens, allowing for the separation of stars. This area is generally more stable, though increasingly devoid of life beyond the dense clusters of the Palm.
