The invention discloses a satellite intermediate inertia axis magnetic control sun capture method and system, and the method comprises the steps: obtaining the sun angle of a satellite safety mode in a continuous time period when a satellite enters a safety mode, determining the sun state of an intermediate inertia axis of the satellite according to the sun angle, and determining that the satellite enters a sun capture mode or a spinning mode according to the sun state. When the satellite enters a sun capture mode; determining a sun-facing state of a middle inertia axis of the satellite according to the main plane solar angle; when the middle inertia axis is located in the sun-facing range, the gyro angular velocity and the solar angle of the satellite are obtained, and whether the satellite enters a spinning mode or is kept in a sun capture mode or not is determined according to the gyro angular velocity and the solar angle; according to the method, the satellite adopts minimum control configuration and energy, the attitude of the satellite is controlled according to the solar angle and the gyro angular velocity of the satellite, it is ensured that a solar panel in a sunny area can efficiently achieve sun capture of a middle inertia axis, and rapid supplementation of satellite energy is achieved.
