The first satellites designed for long term observation of the Sun from interplanetary space were NASA's Pioneers 6, 7, 8 and 9, which were launched between 1959 and 1968. These probes orbited the Sun at a distance similar to that of Earth, and made the first detailed measurements of the solar wind and the solar magnetic field.
It is approximately 24 hours, 39 minutes, 35 seconds long. A Martian year is approximately 668.6 sols, equivalent to approximately 687 Earth days [ 1 ] or 1.88 Earth years. The sol was adopted in 1976 during the Viking Lander missions and is a measure of time mainly used by NASA when, for example, scheduling the use of a Mars rover .
Coordinate systems in astronomy can specify an object's relative position in three-dimensional space or plot merely by its direction on a celestial sphere, if the object's distance is unknown or trivial. Spherical coordinates, projected on the celestial sphere, are analogous to the geographic coordinate system used on the surface of Earth.
Sol is the personification of the Sun and a god in ancient Roman religion.It was long thought that Rome actually had two different, consecutive sun gods: The first, Sol Indiges (Latin: the deified sun), was thought to have been unimportant, disappearing altogether at an early period.
The galactic year, also known as a cosmic year, is the duration of time required for the Sun to orbit once around the center of the Milky Way Galaxy. [1] One galactic year is approximately 225 million Earth years. [2]
The obelisk and the meridian were not originally located in the position in which they were re-erected by the popes, but in the space behind the Curia innocenziana (now called Palazzo Montecitorio). Under the cellar of a stable on a street in the Campus Martius, a piece of the meridian was excavated, with the markings for various months in ...
The Solar Orbiter (SolO) [7] is a Sun-observing probe developed by the European Space Agency (ESA) with a National Aeronautics and Space Administration (NASA) contribution. Solar Orbiter, designed to obtain detailed measurements of the inner heliosphere and the nascent solar wind , will also perform close observations of the polar regions of ...
