Aquarius – Physical – Third Eye: NEPTUNE

Neptune is a planet very similar to Uranus. Both are gas giants with diameters on the order of 4 times that of the Earth, which means that they have volumes about 64 times that of our planet. The masses of Uranus and Neptune are, respectively, 15 and 17 times higher than Earth. Both planets have rocky cores over which extends a mass of hot water that supports, in turn, a dense atmosphere composed mainly of hydrogen and methane. Uranus and Neptune form together with Jupiter and Saturn the group of four outer, giant, gaseous planets. A very different group from the inner group of the four small, rocky planets (Mercury, Venus, Earth, and Mars).

At the Paris Observatory, Urbain Le Verrier (1811-1877), a continuator of the French tradition in «celestial mechanics», was following in Laplace’s footsteps studying the stability of the solar system. When in 1845 François Arago, the director of the observatory, posed the problem of the orbit of Uranus to him, Le Verrier did not wait: in June 1846, on the basis of laborious calculations, he predicted a position for the new planet.

Le Verrier passed his predictions to an astronomer at the Berlin observatory, Johann Galle (1812-1910), who using a refractor built by Fraunhofer located the planet exactly at the position predicted by Le Verrier’s calculations. The discovery was made on the first night Galle attempted it: September 23, 1846. Due to the blue-green color of the planet, Galle named it after the god of the sea: Neptune.

I invite you to read Matias’ post with the topic of the day.

Finally, I encourage everyone to reflect on the concept of the day. No one else but us can re-signify our own being
