A parsec is defined as the distance at which an object has a 1-arcsecond stellar parallax. Where D is the actual distance measured in parsecs and p is the observed parallax angle measured in arcseconds. An astronomical unit, or AU, is equal to the mean (average) distance from the Earth to the Sun, which is about 92,957,000 miles (149,600,000 km). The parallax of a celestial body can be used to find an approximate distance using the formula. However, that distance varies as Earth orbits the Sun, f. Click on an underlined word for more information on that subject. The astronomical unit (symbol au, or ua) is a unit of length, roughly the distance from Earth to the Sun. The kilometer (SI symbol: km) or kilometre (British spelling) is a unit of length in the metric system, equal to 1000 meters (kilo- being the SI prefix for 1000).

Solar System Simulator - "Select from the options.to have the simulator create a color image of your favorite planet or satellite!".It also calculates when a given target lies within 20 degrees of the orbital plane and cannot be observed due to ram Prior to 2012, the astronomical unit was defined as the distance between the center of the Sun at which a tiny particle in an unperturbed circular orbit about the Sun. It was instead a computed value, and it was computed rather strangely. FUSE Continuous Viewing Zone and Orbit Ram Calculator - This calculator can "determine when a given target direction is in the continuous viewing zone. So, when using the Astronomical Unit (AU), problems will begin to surface in astronomical calculations as this universal constant is based on the mass of the Sun There lies the problem. The astronomical unit was defined to be exactly 149 597 870 700 meters in 2012, so it is no longer a measured value.Elliptical Orbit Calculator - Input planetary orbital parameters (semi-major axis, orbital eccentricity and inclination) and and calculate planetary position, area of elliptical orbit and area traversed by the planet.In this calculator we will use units of solar years for time and astronomical units for distance." Using Kepler's Third Law - "Kepler III gives us a very easy way to relate the period of an orbit to its mean radius.It will also plot a graph of the Sun's elevation and bearing over the course of that day." sun position calculator - "This Java®-based Sun position calculator will give the time of sunrise and sunset for any date and location.Lunar Perigee and Apogee Calculator - Calculate the date, time, and distance of lunar perigees and apogees for a given year.
