A multiple star system consists of two or more stars that appear from Earth to be close to one another in the sky. [dubious – discuss] This may result from the stars actually being physically close and gravitationally bound to each other, in which case it is a physical multiple star, or this closeness may be merely apparent, in which case it is an optical multiple star [a] Physical multiple ...
A circumtriple planet is a celestial mass that is hypothesized to be orbiting not only a single star but three stars at the same time. [1] Scientists observing the star system GW Ori , which is a huge disk of dust and gases about 1,300 light years away from Earth, suspect that there may be a circumtriple planet orbiting the three stars.

The system is 530 ± 20 light-years distant from Earth, [12] Eta Normae is a yellow giant of spectral type G8III with an apparent magnitude of 4.65. [15] It shines with a luminosity approximately 66 times that of the Sun. [16] Iota 1 Normae is a multiple star system. The AB (mag 5.2 and 5.76) pair orbit each other with a period of 26.9 years ...
The Kepler-444 system consists of the planet hosting primary and a pair of M-dwarf stars. The M-dwarfs orbit each other at a distance of less than 0.3 AU while the pair orbits the primary in a highly eccentric 324-year orbit. The pair comes within 23.55 AU of the primary potentially truncating the protoplanetary disk from which the planets ...
At the new and full moon, the Sun and Moon are in syzygy. Their tidal forces act to reinforce each other, and the ocean both rises higher and falls lower than the average. [6] Tidal variations can also be measured in the Earth's crust, and these Earth tide influences may affect the frequency of earthquakes.
From the total of 5,086 stars known to have exoplanets (as of January 26, 2024), there are a total of 1,033 known multiplanetary systems, [1] or stars with at least two confirmed planets, beyond the Solar System. This list includes systems with at least three confirmed planets or two confirmed planets where additional candidates have been proposed.
The star is moving so fast that it can complete an orbit 2.5 times the distance between our Earth and the moon in just half an hour. Astronomers discover star orbiting dangerously close to black ...
[3] The possibility of a trojan planet to Kepler-91b was studied but the conclusion was that the transit-signal was a false-positive. [4] In April 2023, a group of amateur astronomers reported two new exoplanet candidates co-orbiting, in a horseshoe exchange orbit, close to the star GJ 3470 (this star has a confirmed planet GJ 3470 b). However ...
