spacecraft to the most easily reached places in our solar system‚ such as Mars. 2. For exploration of celestial bodies‚ NASA has developed a three-phase strategy: reconnaissance‚ surveillance‚ and in-depth study. 3. Each mission to Mars has made specific discoveries and raised questions to be answered by future missions. Materials For this lesson‚ you will need: • Research materials about recent exploration within our solar system • Computer with Internet access

Astronomy Dr. Uskov 03/17/14 Beyond Earth When we were little‚ we got told about different things about our solar system. The belief of such greatness to lie outside of the Earth is almost unbelievable. As for myself‚ I have never really thought of the outside world because I have been so caught up on real life moments that are portrayed as normal such as studying and working. Learning about other planets and other great wonders that happen so many kilometers away is now more than ever mesmerizing

be wandering in the sky‚ the science of Astronomy has broadened this term as well as our understanding of what‚ in fact a planet is. By modern definition‚ “planet” is described as a celestial body other than a star‚ which orbits a star. Our Solar System orbits the center of our home galaxy‚ the Milky Way‚ and has a rich and varied structure. It consists of the Sun‚ four small inner planets‚ four outer gas giant planets‚ and the distant‚ but small planet Pluto. These planets do not wander erratically;

The Lagrange point phenomenon exists in any system wherein the gravitational fields of two large bodies interact to create five “sweet spots”‚ within which lies the exact centripetal force necessary for a smaller object to remain in a constant orbit with the larger objects. There are five Lagrange points within the Sun-Earth orbit‚ as well as five Lagrange points within the Earth-Moon orbit. These points will vary according to the mass of the two larger objects‚ as well as the distance between

Slide 3 What is Saturn? Saturn is the second biggest planet in the solar system with a mean radius of about 58‚ 232 km but it is the least dense planet in the solar system. It’s density is about 0.687 grams per cubic centimetre making it the only planet less dense than water. Saturn spins faster than any other planet except Jupiter‚ completing a rotation roughly every 10 and half hours. The rapid spinning causes Saturn to bulge at its equator and flatten at its poles making it the flattest of the

------------------------------------------------- Introduction Wikijunior books welcomes you to the children ’s book "Solar System". Outer space is perhaps the final frontier for man. Even though the rest of the solar system objects may seem like tiny dots from Earth‚ our celestial neighbors are still important to learn about. The importance of this task has led many experts here at Wikijunior to donate their time and talents to bring this volume together. Wikibooks is a project of the Wikimedia

third-largest planetary radius and fourth-largest planetary mass in the Solar System. Though it is visible to the naked eye like the five classical planets‚ it was never recognized as a planet by ancient observers because of its dimness and slow orbit. It was the first planet to be discovered in modern history. It was discovered in 1781 by Sir William Herschel (Encyclopedia: Uranus (planet)) and expanded the known boundaries of the Solar System for the first time in modern history. Uranus was also the first

Lastly another issue with these so called “rules” is that a planet clearing a orbit depends on the star‚ not just the planet. A system called the scattering parameter gives even more evidence towards pluto being a planet. This
