Phaeton (alternatively Phaethon / ˈ f eɪ. ə θ ən / or Phaëton / ˈ f eɪ. ə t ən /; from Ancient Greek: Φαέθων, romanized: Phaéthōn, pronounced [pʰa.é.tʰɔːn]) is a hypothetical planet hypothesized by the Titius–Bode law to have existed between the orbits of Mars and Jupiter, the destruction of which supposedly led to the formation of the asteroid belt (including the ...
Schematic diagram of the orbits of the fictional planets Vulcan, Counter-Earth, and Phaëton in relation to the five innermost planets of the Solar System.. Fictional planets of the Solar System have been depicted since the 1700s—often but not always corresponding to hypothetical planets that have at one point or another been seriously proposed by real-world astronomers, though commonly ...
The surrounding material is blasted away (f), leaving only a degenerate remnant. [107] When a stellar core is no longer supported against gravity, it collapses in on itself with velocities reaching 70,000 km/s (0.23c), [108] resulting in a rapid increase in temperature and density. What follows depends on the mass and structure of the ...
Multiple telescopes observed a rare cosmic explosion called a kilonova that created heavy elements in space, including some necessary for life. Explosion 1 million times brighter than the Milky ...

Subsequent searches for an alternative Planet X, notably by Robert Sutton Harrington, [52] failed. In 1992, Myles Standish used data from Voyager 2 ' s flyby of Neptune in 1989, which had revised the estimates of Neptune's mass downward by 0.5%—an amount comparable to the mass of Mars—to recalculate its gravitational effect on Uranus.
The stellar eruption will take place in a system called T Coronae Borealis, which is 3,000 light-years away from Earth. ... He likened the nova explosion to a hydrogen bomb detonating in space ...
The team released a paper of their findings dated 27 April 2007, published in the July 2007 journal Astronomy & Astrophysics. [1] At the time of discovery, it was reported to be the first potentially Earth-like planet in the habitable zone of its star [5] [6] and the smallest-known exoplanet around a main-sequence star, but on 21 April 2009, another planet orbiting Gliese 581, Gliese 581e ...
