Explanation:

• Question 6: Jovian planets (Jupiter, Saturn, Uranus, Neptune) are large, gaseous, and have low density. Terrestrial planets (Mercury, Venus, Earth, Mars) are smaller, rocky, and have higher density. Also, Earth is closer to the Sun compared to Jovian planets.
• Question 7: The Sun appears brightest from Earth mainly because it is the closest star. There are stars that are larger, hotter, and newer than the Sun but they are much farther away.
