Sentences with phrase «equatorial plane»
The "equatorial plane" refers to an imaginary flat surface running horizontally and splitting the Earth into two equal halves. It is located at the equator, the line that circles the Earth exactly halfway between the North and South poles. Full definition
In the early 1990s, one study found that coplanarity between the orbital and equatorial planes of nearby binaries (within 100 parsecs or 326 ly) that are composed of Sol - type stars (F5 - K5 V) «exists» for binaries with orbital separations up to the average orbital distance of Pluto in the Solar System — roughly 40 times the Earth - Sun distance or «astronomical unit» (AU).

The disk would have been heavily disturbed by the impact and then would have settled back into the planet's tilted equatorial plane, as a result of friction.
A great question steve, I have looked at this above / below the solar equatorial plane a few times with some neat software made available by semi, so far nothing has surfaced as a possible driver of hemispherical power.
Pulsar wind nebulae (PWN) are produced when the energetic particles streaming from pulsars shoot along the stars» magnetic fields, form tori — donut - shaped rings — around the pulsar's equatorial plane, and jet along the spin axis, often sweeping back into long tails as the pulsars» quickly cut through the interstellar medium.
In 2013, the Kepler spacecraft found two with orbits that are aligned with each other but tilted at about 45 degrees to the equatorial plane of their star, Kepler - 56.
According to the data obtained from the stellar occultation, the ring lies on the equatorial plane of the dwarf planet, just like its biggest satellite, Hi'iaka, and it displays a 3:1 resonance with respect to the rotation of Haumea, which means that the frozen particles which compose the ring rotate three times slower around the planet than it rotates around its own axis.
This revealed «frozen orbits» where a lunar satellite can remain in low orbit indefinitely, inclined at 27 °, 50 °, 76 ° and 86 ° with respect to the moon's equatorial plane.
