Why is this a Lava World?Your planet's proximity to its star (1.00 AU) results in extreme surface temperatures of 4944K.
Lava worlds orbit so close to their stars that rocky surfaces melt into oceans of molten rock. Recent planet formation can also create temporary lava worlds.
Classification Criteria:

Contributing Factors
water3
Very dry - minimal water - boiling away, little would be retained
geology40
Extreme volcanic activity may be hazardous
rotation10
Near tidally locked - one hemisphere perpetually scorched, other frozen, narrow habitable twilight zone only
Organic Chemistry84
Core organic elements (CHNO) present (tidal pools cycle wet and dry - a boost for prebiotic chemistry)
atmosphere4
No atmosphere - exposed to radiation and temperature extremes (partially stripped by slow rotation)
temperature5
Inferno world - temperatures exceed all possibility of life (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))

Surface Characteristics
Molten surface with lava flows, volcanic activity everywhere
Inside the Roche limit (2.80 planet radii): torn apart into a ring system.
Moon 2receding1.1% - 19.8 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Tidal braking locked the planet to its moon: one face forever moonward.
