Within the solar system, the terrestrial planets are the inner planets closest to the Sun, i.e. Our home planet is the third planet from the Sun, and the only place we know of so far thats inhabited by living things. During theformation of the solar system, there were likely more terrestrial planetoids, but they either merged with each other or were destroyed. Because Jupiters radius is about 10% smaller than that of the Sun and its weight is 0.001 times that of the Sun, their densities are comparable. On August 17, a potentially habitable super-Earth HD 85512 b was discovered using the HARPS and a three-super-Earth system known as HD 40307 was also discovered on September 17. **Complete the following terms using the given definitions.
