The International Astronomical Union (IAU) considers an object to be a dwarf planet if:
1. It orbits a star
2. It has enough mass for its gravity to overcome external forces to acquire a near-spherical shape
3. It doesn’t have bigger objects in its neighbourhood
Select the correct option from the codes given below:

Answer: [A] Only 1 & 2

(1) A planet is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighborhood around its orbit.

(2) A “dwarf planet” is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, (c) has not cleared the neighborhood around its orbit, and (d) is not a satellite.

(3) All other objects, except satellites, orbiting the Sun shall be referred to collectively as “Small Solar System Bodies.”
