Compared to theIAU planet definition, planetary scientist Alan Stern’s 2018 definition excludes the first point (that a planet be in orbit around the sun) and the third point (that a planet has cleared the neighborhood around its orbit). Stern’s definition thus counts dwarf planets and plane...
Because the major bodies in the solar system orbit the Sun in nearly the same plane as theecliptic, the position of each planet is predictable and you can plan for photographic opportunities in the future. A suitable telescope that’s mounted to an equatorial mount is capable of high magnifica...
--Spokes and braids in the rings of Saturn--Eddying currents around Jupiter's Great Red Spot--Volcanic eruptions on the satellite Io These are the images from Voyager that have made headlines and captured the public imagination. Now, a giant of twentieth century astronomy guides us on a ...

passed very near to the planets or orbited them closely and sent spectacular images of the surface of the planets, our knowledge increased enormously. Voyager I and Voyager II started their journey in the year 1977, and they have most probably crossed the boundary of the solar system a few ...
the Sun. Hereinafter, we will call Jupiter-like giant planets those objects with massesMlarger or equal than 1MJupiterlying at a distance from their stars between 3 and 12 au (roughly from one to a few times that of the ice line). Note that the lower limit to the mass range is ...
First, biodynamics is based on an animist worldview, regarding the Earth as a living being and the farm as an individual organism in and of itself. Second, it aligns its farming practices with the movements of the Sun, Moon, and other bodies in our cosmos. Third, it uses nine specific ...
The order of the planets in the solar system, starting nearest the sun and working outward is the following: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and then the possible Planet Nine. The solar system stretches outward from the sun, passing the four inner planets, thro...
