The VEGA spacecraft visited the outskirts of Venus during the first stage of its flight. Having left the Earth's gravitational field, it moved along an ellipse with aphelion near the Earth's orbit and perihelion near the orbit of Venus. At what speed relative to Venus did it enter the vicinity of the planet? The known orbital speed of the Earth is Vз = 29.8 km/s and the ratio of the radii of the orbits of Venus and the Earth k = 0.723. The orbits of both planets can be considered circular.
