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 ...
Currently it is the only object with a nearly polar orbit that is in resonance with a planet. [12] Notably, it is part of a group of objects that orbit the Sun in a highly inclined orbit; the reasons for this unusual orbit are unknown as of August 2016. [13] The orbital characteristics of 2011 KT 19 have been compared to those of 2008 KV 42 (Drac).
The Crab Nebula is a pulsar wind nebula associated with the 1054 supernova.It is located about 6,500 light-years from the Earth. [1]A near-Earth supernova is an explosion resulting from the death of a star that occurs close enough to the Earth (roughly less than 10 to 300 parsecs [30 to 1000 light-years] away [2]) to have noticeable effects on Earth's biosphere.
There are several means by which a supernova of this type can form, but they share a common underlying mechanism. If a carbon - oxygen white dwarf accreted enough matter to reach the Chandrasekhar limit of about 1.44 solar masses [ 81 ] (for a non-rotating star), it would no longer be able to support the bulk of its mass through electron ...
The Space Variable Objects Monitor is a small X-ray telescope satellite for studying the explosions of massive stars by analysing the resulting gamma-ray bursts, developed by China National Space Administration (CNSA), Chinese Academy of Sciences (CAS) and the French Space Agency , [45] launched on 22 June 2024 (07:00:00 UTC).
If there's anything on this Earth that you've simply been dying to do or see, you'd best get it done -- and fast.
TRAPPIST-1f, also designated as 2MASS J23062928-0502285 f, is an exoplanet, likely rocky, [2] orbiting within the habitable zone [5] around the ultracool dwarf star TRAPPIST-1, located 40.7 light-years (12.5 parsecs) away from Earth in the constellation of Aquarius.
As of 2000 the majority of scientists agree that Planet X, as Lowell defined it, does not exist. [54] Lowell had made a prediction of Planet X's orbit and position in 1915 that was fairly close to Pluto's actual orbit and its position at that time; Ernest W. Brown concluded soon after Pluto's discovery that this was a coincidence. [55]
