Correct Answer: D
Solution :
[d]| The International Astronautical Unit in 2006 defined the planets in the following three ways |
| 1. Planets are celestial bodies orbiting around the Sur and has sufficient mass for its self gravity to overcome rigid body forces. |
| 2. The dwarf planet is the celestial bodies and having the same properties as defined in point (1). |
| 3. All other object except satellites orbiting around the Sun are referred to as small solar system bodies. |
| Hence, all the statements are correct. |
