List of Bright Comets. This is a list of the bright comets that are currently visible, or that will likely become bright and visible in the future. The longest and shortest days occur at the Solstices. At the Equinoxes, the day is almost exactly the same (12 hours long) all over the world.

This online orrery (Note: an orrery is a machine that shows planetary positions) will hopefully help you to understand what's going on out there. Our live Solar System Map - Getting Oriented Solstice and Equinox Data Courtesy of Fred Espenak, www.Astropixels.com The Zodiac - and "Hey... That planet is in the wrong place!"NASA's New Horizonsspacecraft is currently exploring an icy region beyond Neptune called the Kuiper Belt. It eventually will leave our solar system. For some reason 2 of the 3 online orreries I used to list here are no longer running which is a real shame.

Whether you're an astronomy enthusiast, a student, or simply curious about space, Solar System Simulator offers a captivating and educational experience. It provides a platform for learning about the planets, their moons, and other intriguing phenomena within our solar system. So, embark on this cosmic journey, expand your knowledge of the celestial world, and marvel at the wonders of our own cosmic neighborhood. Indeed the direction the north pole points changes by 1 degree every 72 years (it's called precession), and completes a whole circle about every 26,000 years. This means that although the stars (mainly) stay in the same place, the solstices and equinoxes (which are defined by the movement of the Sun with respect to the Earth's axis) change by 1 degree every 72 years with respect to the stars. And because the position of the zodiac is defined by the equinoxes, it also rotates by 1 degree every 72 years with respect to the stars. Solar System Simulator is an educational game that shows different facts about our galaxy and the planets in it. Switch the view and the information you want to get about each and every planet, like the speed in which Venus travels around the sun, or the Jupiter’s enormous size in kilometers of equatorial circumference. Please note that our simulator provides a simplified and interactive representation of the solar system. While it strives to be accurate and informative, it may not reflect all the complexities and nuances of real-world astronomical phenomena. Find out more interesting facts, explore our magical universe and enjoy Solar System Simulator! List of Bright Asteroids. This list is similar to the list above, and provides constantly updated information about the brightest asteroids and dwarf planets visible in the sky. Experiment with the planets and objects in space, move the planets and see how this affects their orbit and put other objects in their paths such as asteroids and comets. Use your mouse to move around the universe and use all kinds of options to to see what happens enjoying the breathtaking sight. Have fun in Planetarium 2!With lots of 3D features this application allows you to explore the solar system with many basic facts thrown in. It also allows you to see all the stars and constellations. The planets and moons of our solar system come in a wondrous variety of colors and textures. Some appear white, smooth, and calm; others are splotchy with color and dotted with craters and volcanoes. If this is the variety to be found in our solar system, imagine the strange worlds that must exist around other stars!

The apparent size of a planet depends on its size and the distance from Earth. The larger the distance, the smaller the apparent size. NASA explores the unknown in air and space, innovates for the benefit of humanity, and inspires the world through discovery.In this game, you can navigate through space and visit different celestial bodies within the solar system. You can observe their orbits, study their physical features, and even witness astronomical events such as eclipses and planetary alignments. The simulator provides accurate representations of the sizes, distances, and orbital mechanics of the various objects, allowing you to experience the scale and majesty of our cosmic environment.
