The word PLANET is our common intention for today’s Earth contemplation.
This video shows real images of the Earth from Monday June 08, 2020, captured by the NASA/DSCOVR satellite located 1 million miles away.
The term planet is ancient, with ties to history, astrology, science, mythology, and religion. Five planets (Mercury, Venus, Mars, Jupiter and Saturn) in the Solar System are visible to the naked eye. These were regarded by many early cultures as divine, or as emissaries of deities. They are visible for much of the year, except for short periods of time when they are too close to the Sun to observe.
Uranus was discovered in 1781 by Herschel, Neptune in 1846 by Adams & Le Verrier.
In 2006, the International Astronomical Union (IAU) officially adopted a resolution defining planets within the Solar System. This definition is controversial because it excludes many objects of planetary mass based on where or what they orbit. Although eight of the planetary bodies discovered before 1950 remain "planets" under the current definition, some celestial bodies, such as Ceres, Pallas, Juno and Vesta (each an object in the solar asteroid belt), and Pluto (the first trans-Neptunian object discovered), that were once considered planets by the scientific community, are no longer viewed as planets under the current definition of planet.
The first possible evidence of an exoplanet was noted in 1917, but was not recognized as such. The first confirmation of detection occurred in 1992. This was followed by the confirmation of a different planet, originally detected in 1988. As of 1 June 2020, there are 4,268 confirmed exoplanets in 3,154 systems, with 698 systems having more than one planet.
Humankind needed to wait until the Space Age to see the Earth which is sitting under us. The Blueturn project which provides the daily videos for OneHome was the first project to show a video of the Whole Earth rotating.
