Earth and universe Dr.Latifa AL-Naimi 1 Earth Earth ‚ our home planet‚ is beautiful blue and white ball when seen from space. Science is the study of the Earth and its neighbors in space. It is an exciting science with many interesting and practical applications. Some Earth scientists use their knowledge of the Earth to locate and develop energy and mineral resources. Dr.Latifa AL-Naimi 2 Others study the impact of human activity on Earth’s environment and design methods

Approximately 557 Earth years is equal to 1 Eris year. Eris has a diameter between 2‚400 and 3‚000 km. Eris plays a big part in our Solar System and is important to us because it is the largest object and the largest dwarf planet to be found orbiting the sun since 1846‚ when Neptune and its moon Triton was discovered. In conclusion‚ Eris is the 10th planet in our solar system and is rocky unlike many planets before it. References: • Dwarf Planets; UB313 or Eris http://sse.jpl.nasa.gov/planets/profile

The Size of the Solar System Overview • Become familiar with the scale of the planets vs. their distances. • Get an overview of the solar system. Introduction It is easy to flip to the index of an astronomy textbook to discover that‚ say‚ the Sun lies 150 million kilometers away from Earth. It is far more difficult (if not impossible)‚ however‚ to picture this distance in the human mind. In this exercise‚ we will learn to access the often unpalatable distances encountered in astronomy

Most scientists think that our solar system was made from a nearby star‚ called the supernova. These scientists believe that the explosion of the supernova squeezed a nearby cloud of dust‚ causing it to collapse. When the gravity gathered the dust together‚ it formed something called a solar nebula. Soon‚ the cloud became hotter‚ a disk of gas surrounding it. Molecules gathered in a clump as the disk got smaller. Scientists believe in this theory using technology. They used this technology to observe

Solar System Our solar neighborhood is an exciting place. The Solar System is full of planets‚ moons‚ asteroids‚ comets‚ minor planets‚ and many other exciting objects. Learn about Io‚ the explosive moon that orbits the planet Jupiter‚ or explore the gigantic canyons and deserts on Mars. How Did The Solar System form? This is an important question‚ and one that is difficult for scientists to understand. After all‚ the creation of our Solar System took place billions of years before there

The Solar System‚ where the planet Earth belongs‚ is formed by: a start known as the sun‚ four inner planets‚ Mercury‚ Venus‚ Earth and Mars‚ and five outer planets‚ Jupiter‚ Saturn‚ Uranus‚ Neptune and Pluto‚ over 60 satellites or moons‚ more than 5‚000 asteroids‚ numerous comets‚ and smaller interplanetary dust and debris (“Astronomy n.pag). The way that all this elements of the Solar System interact and move around the Sun seems to be perfectly synchronized but‚ how did it began? What was it

Planets and moons in our solar system share many similar properties‚ but there are also many ways they are different. Some of the main differences come with the different geologic activity‚ composition‚ interior structure‚ magnetic field‚ and atmosphere that distinguish some planets and moons from others. The first way to separate the planets as far as their surfaces is breaking them into their two categories. The Jovian planets (Jupiter‚ Saturn‚ Uranus‚ Neptune) are primarily composed of gas and

Inside the Solar System: Comet C/2011 N3 PSC 103 - Astronomy Summer 2012 According to an article written in early January Scientific American (Matson‚ 2012)‚ on July 6th‚ for the first time ever‚ a sun-watching spacecraft has traced a comet’s route directly into the sun. The magazine boasts this as the “Solar Swan Song” (Matson‚ 2012) and compares this comet’s demise to dramatic exits in the movie Dr. Strangelove. Discovered by the Solar and Heliospheric Observatory‚ otherwise known as SOHO

Solar Nebular Hypothesis The idea behind the Solar Nebular Hypothesis is that the solar system was condensed from an enormous cloud of hydrogen‚ helium‚ and a few other elements and rocks. Around five billion years this cloud of materials began to spin and contract together into a disk shape under their own gravitational forces. The particles started combined together‚ protoplanets‚ to eventually form planets. A great mass of the material eventually began to form together‚ protosun‚ and make
