SUMMARY
The minimum speed required for a spacecraft to escape the solar system from Earth's orbit is determined primarily by the gravitational influences of the Sun and Earth. The escape speed can be calculated using the formula v_e = √(2GM/r), where M is the mass of the celestial body and r is the distance from its center. The gravitational effects of other planets, such as Jupiter and Neptune, are negligible when considering escape velocity, as they are far enough away. The discussion emphasizes the importance of understanding gravitational potential energy and kinetic energy conservation in deriving escape velocity.
