Presentation at ESWW11, Liege, November 17-22, 2014. CONTENTS:. Motivation. Introduction. Orbital Parameters. Earth’s gravity pulls objects toward the center of Earth.. No matter where you stand on Earth. The direction of down will be toward Earth’s center.. As Earth turns, so do we. Earth rotates around on an imaginary lime running through its center called an “axis of rotation”.. Lecture 3. ENGR. MARVIN JAY T. SERRANO. lecturer. PROBLEM 1. Compute the latitude of the place of observation when the observation of Polaris is at upper culmination. ALTITUDE: DIRECT: . 12-38. REVERSE: . How do we know the Earth goes around the Sun?.

To find the velocity increment required for various missions, we must calculate trajectories and orbits. This is done using Newton's Law of Gravitation: . What Is an Orbit?. Johannes . Kepler. discovered (in . 1600s. ) that planets orbit in . ellipses, . not . circles.. Satellites (natural or . human-made. ) also orbit Earth in elliptical . pattern.. Elliptical orbits remain fixed in space and Earth spins under a fixed satellite . First things first…. Rotation. . – a circular movement of an object around a . center. (or . point. ) . of rotation; rotation around an axis. Sidereal Day – The time it takes for a planet to make one . What Is an Orbit?. Johannes . Kepler. discovered in . 1600s . that . planet orbits form . ellipses, . not . circles.. Satellites (natural . or . human-made) orbit Earth as an ellipse.. Elliptical . orbits remain . and Earth.

Astronomers use light years since the distances in space are so large that, if expressed in km or m, the numbers would be mind boggling.. Light travels 7.5times around the earth in one second.. 1light-year = 9.461×10.
