How Many Spacecraft Have Left the Solar System?

💡 The Answer

• Voyager 2 is the third of five spacecraft to achieve solar escape velocity.
• This allows it to leave the Solar System entirely.
• The other four include Pioneers 10 and 11, Voyager 1, and New Horizons.
• Achieving escape velocity means it will never return to the Sun's orbit.
• Voyager 2's extended mission studies interstellar space beyond the heliosphere.
