Why is this a Earth Like?Your planet has a balanced composition with all CHNOPS elements, proper mass (1.0x Earth), and sits in the habitable zone at 23.20 AU.
Earth-like planets have the perfect combination of composition, temperature, mass, and magnetic field to potentially support complex life as we know it.
Classification Criteria:
✓ All CHNOPS elements present (C, H, N, O, P, S)✓ Mass: 1.0x Earth (0.5-2.0x range)✓ Temperature: 258K (250-320K range)✓ Magnetic field present✓ Distance: 23.20 AU (habitable zone)

Contributing Factors
water50
Limited water content
geology100
Active geology recycles nutrients and drives carbon cycle (tidal flexing sustains geologic activity)
rotation10
Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only
Organic Chemistry80
Core organic elements (CHNO) present
atmosphere40
Nitrogen-oxygen atmosphere - breathable and protective (partially stripped by slow rotation)
temperature75
Challenging but potentially habitable temperature (large moon stabilizes the axial tilt - steady seasons)
magnetic Field100
Magnetic field provides radiation protection (a large close moon may help stir the core dynamo (speculative)) — but the black hole's accretion disk bathes this orbit in hard X-ray radiation

Outside the synchronous orbit: slowly receding, like Luna (~cm per year).

Tidal braking locked the planet to its moon: one face forever moonward.
