Planet Nine is a hypothetical ninth planet in the outer region of the Solar System. [4] [2] Its gravitational effects could explain the peculiar clustering of orbits for a group of extreme trans-Neptunian objects (ETNOs), bodies beyond Neptune that orbit the Sun at distances averaging more than 250 times that of the Earth i.e. over 250 astronomical units (AU).
The Gregorian calendar will be a full day ahead of the solar year. 3,984 6009 The first Strobogrammatic numbered year since 1961. 10,000 12025 The Gregorian calendar will have drifted by about 10 days in relation to the seasons. [164] 10,867 June 10, AD 12,892
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
Scientists say they have found new evidence that there is a hidden planet in our solar system. For years, some astronomers have been suggesting that unusual behaviour on the edge of our solar ...
The number of known planets in our solar system has risen and fallen over time. Planet nine may be orbiting far from the Sun, at the edge of our solar system. Astronomers, seeing odd ...
The distance separating the two planets in the sky will be less than the width of a pinky finger held out at arm's length. The planetary convergence is one of the top astronomy events of 2023.
After all his 1988 predictions failed to come true, Whisenant revised his prediction date to this day. [131] [132] 23 Apr 1990 Elizabeth Clare Prophet: Prophet predicted a nuclear war would start on this day, and the world would end 12 years later, leading her followers to stockpile a shelter with supplies and weapons.
Nineteen moons are large enough to be round, and two, Titan and Triton, have substantial atmospheres The number of moons discovered in each year until November 2019. Mercury, the smallest and innermost planet, has no moons, or at least none that can be detected to a diameter of 1.6 km (1.0 mi). [2]
