Question

All the planets in the solar system revolve around the Sun in same plane. This statement is

• A. True
• B. False

Answer 1

The correct option is A True

Most of the planets orbit the Sun very near the same plane in which the Earth orbits, the ecliptic.
The orbits of the planets are ellipses with the Sun at one focus, though all except Mercury are very nearly circular. The orbits of the planets are all more or less in the same plane (called the ecliptic and defined by the plane of the Earth's orbit). The ecliptic is inclined only 7 degrees from the plane of the Sun's equator.
Hence, the statement is true.
