Since then, astronomers have found thousands more. In the comic, our {{w|Solar System}}'s eight planets are depicted in the small rectangle above the central text. From this we find that the largest dots (red) and second largest dots (dark brown) indicate planets larger than Jupiter, light brown is roughly {{w|Jupiter}} or {{W|Saturn}}-sized, blue is roughly {{w|Uranus}} or {{w|Neptune}}-sized, and the tiny dots are small {{w|terrestrial planets}} (like {{w|Earth}}). | Since then, astronomers have found thousands more.
