The Earth's orbit has a radius of 1.5-10 m, and that of Venus has a radius of 1.1 ∙ 1011 m. Consider these two orbits to be perfect circles (though in reality they are ellipses with slight eccentricity). Write the direction and length of a vector from Earth to Venus (take the direction from Earth to Sun to be 0°) when Venus is at the maximum angular separation in the sky relative to the Sun.
