Sentences with phrase «orbital plane»
The phrase "orbital plane" refers to the imaginary flat surface in space along which a celestial object, such as a planet or satellite, travels in its orbit around another object. It is like a path or track that the object follows as it goes around. Full definition

Axial tilt is an astronomical term regarding the inclination angle of a planet's rotational axis in relation to a perpendicular to its orbital plane.
The axial tilt may equivalently be expressed in terms of the planet's orbital plane and a plane perpendicular to its axis.
In our solar system, the Earth's orbital plane is known as the ecliptic, and so the Earth's axial tilt is officially called the obliquity of the ecliptic.
The axial tilt is expressed as the angle made by the planet's axis and a line drawn through the planet's center perpendicular to the orbital plane.
A line drawn from this opening forms an acute angle with a line running through the eye socket (known as the orbital plane).
The tilt of the solar system's orbital plane has long befuddled astronomers because of the way the planets formed: as a spinning cloud slowly collapsing first into a disk and then into objects orbiting a central star.
Planet Nine, based on their calculations, appears to orbit at about 30 degrees off from the other planets» orbital plane in the process, influencing the orbit of a large population of objects in the Kuiper Belt, which is how Brown and Batygin came to suspect a planet existed there in the first place.
The seasons result from the Earth's axis being tilted to its orbital plane; it deviates by an angle of approximately 23.44 degrees.

«The planets are small, they have circular orbits, their orbital planes are flat — it starts to look like home very quickly,» says Jason Rowe of the SETI Institute in Mountain View, California.
They all line up with each other obediently enough, but their orbital plane is slightly offset from the sun's equator.
About twice a year the camera will capture the moon and Earth together as the orbit of DSCOVR crosses the orbital plane of the moon.
Since the rotation axis of Saturn inclines compared to its orbital plane around the Sun, the ring opening angle to the Sun changes over a 15 - year cycle.
«Its orbit flips essentially randomly relative to the orbital plane of its star,» Cameron says, potentially turning over completely.
In order to witness a transit, the orbital plane of the planets must be at or near our line of vision, but not all solar systems have the same orientation.
In a paper accepted for publication in Astrophysical Journal, lead author David Fleming, a UW astronomy doctoral student, studies eclipsing binaries, or those where the orbital plane is so near the line of sight, both stars are seen to cross in front of each other.
Such changes are much less pronounced than the seasonal changes on Earth because Jupiter's equator is inclined at only 3.2 ° to its orbital plane whereas Earth's is at 23.5 °.
The same kick can change the alignment of smaller black holes and rock their orbital plane.
There are 11 satellites in each of six orbital planes and their paths intersect roughly over the North and South poles.
Having three detectors also enables researchers to make a rough measurement of the wave's polarization — a property that indicates how the black holes» orbital plane (the plane on which they rotate around each other) is orientated with respect to Earth.
One phenomenon that Sathyaprakash is eager to observe is a «precession» of the black holes» orbital plane, meaning that their paths trace a kind of 3D rosette.
But orbital precession occurs only when two black holes have axes of rotation that point in random directions, and it disappears when the axes are both perpendicular to the orbital plane.
The different Q values also allow the planets to re-align their orbits with the spin of the star (so that the orbital plane is perpendicular to the star's spin axis) on a timescale shorter than the orbital period decay, thus explaining why there are many «aligned» hot Jupiters.
In 2006, astronomers discovered a very dim («mid-range»), red dwarf companion to HD 189733 A of spectral and luminosity type M V. Observed at a separation of 216 AUs from Star A, the companion star has a clockwise orbit that is nearly perpendicular to the orbital plane of transiting planet b around Star A (HD 189733 b or Ab).
Martian eccentricity is about 0.1 — over 5 times larger than Earth's, so the insolation (INcoming SOLar radiATION) variation over the orbit is substantial, and contributes significantly more to seasonality than on the Earth, although Mars's obliquity (the angle of its spin axis to the orbital plane) still dominates the seasons.
The Cygnus - Lyra neighborhood was chosen as the study area because it's well - populated with stars and lies high enough above the Earth's orbital plane that the sun, Earth and moon won't get in the way of Kepler's observations.
Furthermore, it also provides evidence that suggests that at least one of the black holes may have been tilted away from the orbital plane at the time of the merger, the study authors added.
