Solar System 2 Pdf Total mass of the solar system. about three quarters of the sun consists of hydrogen; the rest is mostly helium. less than 2% consists of heavier elements, including oxygen, carbon, gold, iron, and others. many of these elements were originally forged in supernova explosions. so we, and everything in our solar system, are made of “star stuff”2. 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 uranus and neptune are.
Solar System Pdf Pdf Solar System Planets The solar system unit overview our solar system is home to earth and seven other planets. each planet rotates on its axis while revolving around the sun. each planet has unique characteristics and qualities that set it apart from the others. the sun keeps this complex arrangement in order. the solar system unit reveals detailed. Travel times by spacecraft around the solar system . 1.3 . most science fiction stories often have spaceships with powerful, or exotic, rockets that can let space travelers visit the distant planets in less than a day’s journey. the sad thing is that we are not quite there in the real world. this is because our solar system is so.
