Planets For Kids - Solar System Facts and Astronomy Planet Facts Read some really neat facts about the planets in our solar system! © Contributed by Leanne Guenther Note: The fast facts on this page are appropriate for grades 1 to 3 while the "more about" links are appropriate for grades 4+. I've listed them in order from closest to furthest from the sun: Mercury Venus Earth Mars Ceres (dwarf planet found in the asteroid belt) Jupiter Saturn Uranus Neptune Pluto (Note: Pluto is considered a dwarf planet now) Eris, Makemake, Haumea, Sedna (also dwarf planets -- found past Pluto) Mercury takes 59 days to make a rotation but only 88 days to circle the Sun. Many astronomers believe that Mercury might be the core of what was once a much larger planet -- it appears to be a huge ball of iron covered by a thin layer of rock. Venus is the brightest planet in our sky and can sometimes be seen with the naked eye if you know where to look. Earth has more exposed water than land. On-Line Jigsaw Puzzles: Between Mars and Jupiter, is a Dwarf Planet known as Ceres.
World Sunlight Map Watch the sun rise and set all over the world on this real-time, computer-generated illustration of the earth's patterns of sunlight and darkness. The clouds are updated daily with current weather satellite imagery. The Mercator projection used here is one way of looking at the spherical earth as a flat map. Used since the 16th century for navigation, straight lines on this map can be used accurately as compass bearings but the size and shape of continents are distorted. Compare this with Peters, Mollweide or equirectangular projection maps. Also available is a semi-realistic view of dawn and dusk from far above the Earth, a look at the moon, and information about how this works.
10 Best Places to Live for Escaping World Conflict | Expatify - StumbleUpon Where would you be the safest if World War 3 broke out tomorrow? Perhaps it’s a grim subject, but safety and distance from world conflict can be a motivating factor in your choice to expatriate. At the very least, conflict around the world can weigh heavy on the soul, and it’s nice to know there are some places still left in the world where you might be left in peace.

Switzerland’s long history of neutrality and its tucked away location among the valleys of the Alps still make it a safe bet, even despite having a high number of bordering nations. 9. Costa Rica has a stable democracy, a disbanded military and a national policy of neutrality. 8. There are regions of Papua New Guinea that are still being discovered for the first time. 7. Canada is the second largest nation in the world, yet it only shares a land border with one other country– the U.S.A.– and it is a peaceful border. 6. 5.
The 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. What Is The Solar System? The Solar System is made up of all the planets that orbit our Sun. Everything in the Solar System orbits or revolves around the Sun. How Did The Solar System form? This is an important question, and one that is difficult for scientists to understand. Scientists believe that the Solar System evolved from a giant cloud of dust and gas. At the center of this spinning cloud, a small star began to form. Further away from the center of this mass where the star was forming, there were smaller clumps of dust and gas that were also collapsing. A Great Storm Once ignited, the Sun's powerful solar winds began to blow. The Solar System Has Over 100 Worlds It is true that there are only eight planets.
solarsystem.nasa There are more planets than stars in our galaxy. The current count orbiting our star: eight. The inner, rocky planets are Mercury, Venus, Earth, and Mars. NASA's newest rover — Perseverance — landed on Mars on Feb. 18, 2021. Beyond Neptune, a newer class of smaller worlds called dwarf planets reign, including longtime favorite Pluto. Planets of our Solar System Mercury Mercury—the smallest planet in our solar system and closest to the Sun—is only slightly larger than Earth's Moon. Venus Venus spins slowly in the opposite direction from most planets. Earth Earth—our home planet—is the only place we know of so far that’s inhabited by living things. Mars Mars is a dusty, cold, desert world with a very thin atmosphere. Jupiter Jupiter is more than twice as massive than the other planets of our solar system combined. Saturn Adorned with a dazzling, complex system of icy rings, Saturn is unique in our solar system. Uranus Neptune What is a Dwarf Planet? Real-Time, Interactive Solar System

Ancient astronomers observed points of light that appeared to move among the stars. Since the invention of the telescope, three more planets have been discovered in our solar system: Uranus (1781), Neptune (1846), and, now downgraded to a dwarf planet, Pluto (1930). The four planets closest to the sun—Mercury, Venus, Earth, and Mars—are called the terrestrial planets because they have solid rocky surfaces. Nearly every planet—and some of the moons—has an atmosphere. Moons, Rings, and Magnetospheres There are 140 known natural satellites, also called moons, in orbit around the various planets in our solar system, ranging from bodies larger than our own moon to small pieces of debris. From 1610 to 1977, Saturn was thought to be the only planet with rings. Most of the planets also have magnetic fields, which extend into space and form a magnetosphere around each planet.
Britannica School Scientists measure dream content for the first time: Dreams activate the brain in a similar way to real actions The ability to dream is a fascinating aspect of the human mind. However, how the images and emotions that we experience so intensively when we dream form in our heads remains a mystery. Up to now it has not been possible to measure dream content. They were able to do this with the help of lucid dreamers, i.e. people who become aware of their dreaming state and are able to alter the content of their dreams. The research is published in the journal Current Biology. Methods like functional magnetic resonance imaging have enabled scientists to visualise and identify the precise spatial location of brain activity during sleep. Scientists from the Max Planck Institute of Psychiatry in Munich, the Charité hospital in Berlin and the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig availed of the ability of lucid dreamers to dream consciously for their research.
