Per NCERT §7.2 (1st law), Kepler's law of orbits states that each planet moves in which kind of orbit around the Sun?
ACircle centred on the Sun
BEllipse with Sun at one focus
CParabola through the Sun
DHyperbola with focus at the Sun
Answer & Solution
Correct answer: B. Ellipse with Sun at one focus
