Kinetic simulations of finite gyroradius effects in the lunar plasma environment on global, meso, and microscales

► We examine finite gyroradius effects in the solar wind interaction with the Moon. ► Global scale interaction and magnetic anomalies are studied with a 3D hybrid model. ► The potential sheath is studied with an electrostatic 1D Particle-in-Cell simulation. ► The finite ion and electron gyroradius was found to affect lunar plasma environment. ► Kinetic effects should be taken into account in lunar plasma models.
