Solar System their mass, orbit, and distance from the Sun, with a possibly significant contribution from comets. The Sun, which comprises nearly all the matter in the Solar System, is composed of roughly 98% hydrogen and helium. Jupiter and Saturn, which comprise nearly all the remaining matter, are also primarily composed of hydrogen and helium. A composition gradient exists in the Solar System, created by heat and light pressure from the Sun; those objects closer to the Sun, which are more affected by heat and light pressure, are composed of elements with high melting points. Objects farther from the Sun are composed
Monument to the Sun time because the planet installations would have to be from a few hundred meters to several tens of kilometers away from the Sun. Beneath the glass are photo-voltage solar modules with lighting elements which turn on at night, and produce show of light. On the chrome ring that surrounds the photo-voltage solar modules on the Sun, are inscribed the names of all of the saints after which present and previous churches on the Zadar peninsula have been named. Next to their names and the date of their feast are the declination and the altitude of the Sun north or south
