The Sun is currently 5–30 parsecs (16–98 ly) above, or north of, the central plane of the Galactic disk. [104] The distance between the local arm and the next arm out, the Perseus Arm, is about 2,000 parsecs (6,500 ly). [105] The Sun, and thus the Solar System, is located in the Milky Way's galactic habitable zone. [106] [107]
Quadrants are described using ordinals—for example, "1st galactic quadrant", [1] "second galactic quadrant", [2] or "third quadrant of the Galaxy". [3] Viewing from the north galactic pole with 0 degrees (°) as the ray that runs starting from the Sun and through the galactic center, the quadrants are as follows (where l is galactic longitude):
The Carrington heliographic coordinate system, established by Richard C. Carrington in 1863, rotates with the Sun at a fixed rate based on the observed rotation of low-latitude sunspots. It rotates with a sidereal period of exactly 25.38 days, which corresponds to a mean synodic period of 27.2753 days.
The galactic coordinate system uses the approximate plane of the Milky Way Galaxy as its fundamental plane. The Solar System is still the center of the coordinate system, and the zero point is defined as the direction towards the Galactic Center. Galactic latitude resembles the elevation above the galactic plane and galactic longitude ...
In astronomy, the ecliptic coordinate system is a celestial coordinate system commonly used for representing the apparent positions, orbits, and pole orientations [1] of Solar System objects. Because most planets (except Mercury ) and many small Solar System bodies have orbits with only slight inclinations to the ecliptic , using it as the ...
California Democratic Gov. Gavin Newsom asked state lawmakers Monday for an additional $25 million in funding to cover the cost of legal battles he expects to have with President-elect Donald ...
The four quadrants of a Cartesian coordinate system The axes of a two-dimensional Cartesian system divide the plane into four infinite regions , called quadrants , each bounded by two half-axes. The axes themselves are, in general, not part of the respective quadrants.
The Colonels were later up 25-21 on a 3-pointer by Sincere Malone with 7:11 left before Gonzaga took over. Huff scored five straight points to put the Bulldogs ahead, before Nicholls regained the ...
