      Our solar system formed about 4.6 billion years ago. The four . planets closest to the Sun — Mercury, Venus, Earth, and Mars — are called the terrestrial planets because they have solid, rocky surfaces. Two of the outer planets beyond the orbit of Mars — Jupiter and Saturn — are known as gas giants; the more distant
