where β g {\displaystyle \beta _{g}} = 27° 07′ 42.01″ and α g {\displaystyle \alpha _{g}} = 12h 51m 26.282s are the declination and right ascension of the north galactic pole, [231] whereas β e {\displaystyle \beta _{e}} = 66° 33′ 38.6″ and α e {\displaystyle \alpha _{e}} = 18h 0m 00s are those for the north pole of the ecliptic. (Both pairs of coordinates are for J2000 epoch.) The result of the calculation is 60.19°. The scattered disc, which overlaps the Kuiper belt but extends out to near 500 AU, is thought to be the source of short-period comets. Scattered-disc objects are believed to have been perturbed into erratic orbits by the gravitational influence of Neptune's early outward migration. Most scattered disc objects (SDOs) have perihelia within the Kuiper belt but aphelia far beyond it (some more than 150AU from the Sun). SDOs' orbits can also be inclined up to 46.8° from the ecliptic plane. [177] Some astronomers consider the scattered disc to be merely another region of the Kuiper belt and describe scattered-disc objects as "scattered Kuiper belt objects". [178] Some astronomers also classify centaurs as inward-scattered Kuiper belt objects along with the outward-scattered residents of the scattered disc. [179] Eris and Gonggong

The Kuiper belt is a great ring of debris similar to the asteroid belt, but consisting mainly of objects composed primarily of ice. [156] It extends between 30 and 50AU (4.5 and 7.5billionkm; 2.8 and 4.6billionmi) from the Sun. It is composed mainly of small Solar System bodies, although the largest few are probably large enough to be dwarf planets. [157] There are estimated to be over 100,000 Kuiper belt objects with a diameter greater than 50km (30mi), but the total mass of the Kuiper belt is thought to be only a tenth or even a hundredth the mass of Earth. [44] Many Kuiper belt objects have satellites, [158] and most have orbits that are substantially inclined (~10°) to the plane of the ecliptic. [159] Depending on the model you choose, star projectors can recreate the night sky accurately from the comfort of your own home, surrounding you with stars, constellations and double as galaxy projectors. Whether you’re hosting a space-themed party, learning about the cosmos or simply looking for a way to help you fall asleep, star projectors can do it all.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 Blisslights Sky Lite 2.0 A fun way to see and create lights that are comparable to deep space imagery and stars, albeit not scientific. Ideal for creating a relaxing mood in the home.★★★½ In theory, yes. Most models of star projectors run from mains AC power or DC through a USB port, so they will run as long as they are plugged in. Some models are battery-powered, meaning you run the risk of the battery running out of power overnight. 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! In comparison to the Atmosphere Smart Galaxy Projector, the Ambience Galaxy & Star Projector has fewer lighting modes available, but it doesn't suffer for it. It offers four colors: blue, green, white and red, and users can blend these colors using the supplied remote control and adjust the brightness to their preference.

Considering its reasonable price tag and the many educational benefits it offers, we believe this projector is a worthwhile investment for homeschooling or simply learning about space with your child. Despite its compact size and unassuming appearance, this USB-powered projector is powerful for transforming any room into a celestial-like wonderland. When connected to a USB power source, it projects hundreds of laser stars in a single color, creating a truly immersive and atmospheric experience. Whether you're a gamer looking to enhance your gaming environment, a parent looking to create a magical bedtime routine for your child (ensure they can't look directly into the beam), or simply someone who appreciates the beauty of the cosmos, this star projector will surely delight. It serves no other purpose or provides any scientific accuracy. Still, it is a discrete, affordable, high-quality device that puts out visually stunning lasers to transform your surroundings while drawing very little energy.Star projectors come in different shapes, specifications and sizes because they serve various purposes. Some models are designed as night lights for children, so they are simpler and prioritize creating a pleasant atmosphere rather than realistic star patterns. On the other hand, there are highly accurate star projectors that provide a scientific representation of the night sky, giving you the experience of being inside a planetarium. Earth's magnetic field also stops its atmosphere from being stripped away by the solar wind. [74] Venus and Mars do not have magnetic fields, and as a result the solar wind causes their atmospheres to gradually bleed away into space.

As we confirmed in our BlissLights Evolve review, the operation is near silent like the Sky Lite 2.0. The Bliss Lights Sky Lite Evolve would be perfect in a gaming room, during a party, at a movie night or as a relaxation tool to unwind or drift off to sleep with. There are three models in the range — blue, green, or no lasers.

Rotating the image and adjusting the focus wheel in the dark is simple thanks to the blue-illuminated buttons. The result is a bright and sharp projection on the ceiling (the optics are from the German optics brand Bresser, which makes binoculars, telescopes, and microscopes). However, stars at the edge of the projection can seem blurry. One novel feature is an optional 'falling star' mode, which projects a flashing meteor every 40 seconds, though always in the same place. The Sky Lite 2.0 is best compared to the likes of a lava lamp in terms of what it tries to achieve. This star projector delivers if a hypnotic journey through an imaginary nebula (or aurora?) is the effect you're after. Once again, we're not sure what we love most about this feature-rich Aurora Borealis Northern Lights Star Projector. You can easily choose between a whopping 16.7 million Aurora colors by using the buttons on the device, the remote control that comes with it or your smartphone to control it. Main article: Discovery and exploration of the Solar System The motion of 'lights' moving across the sky is the basis of the classical definition of planets: wandering stars.The dwarf planet Pluto (with an average orbit of 39AU (5.8billionkm; 3.6billionmi) from the Sun) is the largest known object in the Kuiper belt. When discovered in 1930, it was considered to be the ninth planet; this changed in 2006 with the adoption of a formal definition of planet. Pluto has a relatively eccentric orbit inclined 17 degrees to the ecliptic plane and ranging from 29.7AU (4.44billionkm; 2.76billionmi) from the Sun at perihelion (within the orbit of Neptune) to 49.5AU (7.41billionkm; 4.60billionmi) at aphelion. Pluto has a 2:3 resonance with Neptune, meaning that Pluto orbits twice round the Sun for every three Neptunian orbits. Kuiper belt objects whose orbits share this resonance are called plutinos.
