Notes
binary star/binary system a binary star is a star system consisting of two stars orbiting around their common barycenter. These systems, especially when more distant, often appear to the unaided eye as a single point of light, and are then revealed as multiple by other means. 1, 3, 4, 5, 9, 12, 13, 14, 15, 17, 18, 19, 20, 21, 24, 27, 28 [T 2]
[WPT 1]
adaptive optics a technology used to improve the performance of optical systems by reducing the effect of incoming wavefront distortions by deforming a mirror in order to compensate for the distortion. It is used in astronomical telescopes to remove the effects of atmospheric distortion. 1 [T 3]
[WPT 2]
apparent magnitude a number that is a measure of its brightness as seen by an observer on Earth. The brighter an object appears, the lower its magnitude value (i.e. inverse relation). 35 [T 4]
[WPT 3]
Shack-Hartmann principle an optical instrument used for characterizing an imaging system. It is a wavefront sensor commonly used in adaptive optics systems. Shack–Hartmann sensors are used to characterize eyes for corneal treatment of complex refractive errors. 1 [T 2]
[WPT 4]
Equation of Time the discrepancy between two kinds of solar time. The word equation is used in the medieval sense of "reconcile a difference". The two times that differ are the apparent solar time, which directly tracks the diurnal motion of the Sun, and mean solar time, which tracks a theoretical mean Sun with noons 24 hours apart. 26 [T 5]
[WPT 5]
Sothic cycle a period of 1,461 Egyptian civil years of 365 days each or 1,460 Julian years averaging 365¼ days each. During a Sothic cycle, the 365-day year loses enough time that the start of its year once again coincides with the heliacal rising of the star Sirius on 19 July in the Julian calendar. 25, 33 [T 6]
[WPT 6]
analemma a diagram showing the variation of the position of the Sun in the sky over the course of a year, as viewed at a fixed time of day and from a fixed location on the Earth. 26 [T 5]
[WPT 7]
sidereal year the time taken by the Earth to orbit the Sun once with respect to the fixed stars. 31 [T 7]
[WPT 8]
sidereal day approximately 23 hours, 56 minutes, 4.0905 SI seconds. The sidereal day is 0.0084 seconds shorter than Earth's period of rotation relative to the fixed stars. 31 [T 7]
[WPT 9]
solar year/tropical year the time that the Sun takes to return to the same position in the cycle of seasons, as seen from Earth; for example, the time from vernal equinox to vernal equinox, or from summer solstice to summer solstice. 31 [T 7]
[WPT 10]
solar day/civil day 31 [T 7]
[WPT 11]
anomalistic year the time taken for the Earth to complete one revolution with respect to its apsides. Its average duration is 365.259636 days (365 d 6 h 13 min 52.6 s). 31 [T 7]
[WPT 12]
tidal locking occurs when the long-term interaction between a pair of co-orbiting astronomical bodies drives the rotation rates into a harmonic ratio with the orbital period. 11 [T 8]
[WPT 13]
aberration of light an astronomical phenomenon which produces an apparent motion of celestial objects about their true positions, dependent on the velocity of the observer. Aberration causes objects to appear to be displaced towards the direction of motion of the observer compared to when the observer is stationary. 34 [T 9]
[WPT 14]
apparent retrograde motion the apparent motion of a planet in a direction opposite to that of other bodies within its system, as observed from a particular vantage point. Direct motion or prograde motion is motion in the same direction as other bodies. 5, 6, 7, 9 [WPT 15]
apsidal precession the precession (rotation) of the orbit of a celestial body. More precisely, it is the gradual rotation of the line joining the apsides of an orbit, which are the points of closest and farthest approach. 28 [T 10]
[WPT 16]
axial tilt the angle between an object's rotational axis and its orbital axis, or, equivalently, the angle between its equatorial plane and orbital plane. 8 [T 11]
[WPT 17]
circumbinary a planet that orbits two stars instead of one. Because of the short orbits of some binary stars, the only way for planets to form is by forming outside the orbit of the two stars. 9, 14, 29 [WPT 18]
equinoctial precession a change in the orientation of the rotational axis of a rotating body. In astronomy, precession refers to any of several slow changes in an astronomical body's rotational or orbital parameters. An important example is the steady change in the orientation of the axis of rotation of the Earth, known as the precession of the equinoxes. 22 [T 12]
[WPT 19]
[WPT 20]
astronomical unit (AU) a unit of length, roughly the distance from Earth to the Sun. However, that distance varies as Earth orbits the Sun, from a maximum (aphelion) to a minimum (perihelion) and back again once a year. Originally conceived as the average of Earth's aphelion and perihelion, it was defined exactly as 149,597,870,700 metres or about 150 million kilometres (93 million miles) since 2012. 5, 15, 17, 26, 32, 33, 36 [WPT 21]
right ascension (RA) [WPT 22]
declination (DECL) [WPT 23]
perigee [WPT 24]
apogee [WPT 24]
perihelion [WPT 25]
aphelion [WPT 25]
conjunction (inferior/superior) [WPT 26]
prograde [WPT 27]
retrograde [WPT 27]
equinox [WPT 28]
solstice [WPT 29]
proper motion the astronomical measure of the observed changes in the apparent places of stars or other celestial objects in the sky, as seen from the center of mass of the Solar System, compared to the abstract background of the more distant stars. 36 [T 13]
[WPT 30]
radial velocity the rate of change of the distance between the object and the point. That is, the radial velocity is the component of the object's velocity that points in the direction of the radius connecting the object and the point. In astronomy, the point is usually taken to be the observer on Earth, so the radial velocity then denotes the speed with which the object moves away from or approaches the Earth. 36 [T 13]
[WPT 31]
Michelson-Morley experiment experiment performed between April and July, 1887 by Albert A. Michelson and Edward W. Morley in Cleveland, Ohio. It compared the speed of light in perpendicular directions, in an attempt to detect the relative motion of matter through the aether. The result was negative, in that the expected difference between the speed of light in the direction of movement through the presumed aether, and the speed at right angles, was found not to exist. 19 [T 14]
[WPT 32]
General Relativity (GR) the geometric theory of gravitation published by Albert Einstein in 1915 and the current description of gravitation in modern physics. 28 [T 10]
[WPT 33]
Binary Research Institute The Binary Research Institute was formed in 2001 to support and fund research regarding the hypothesis that the Sun is part of a binary star system. 1, 14, 18, 24, 30 [1]
NEAVE planetarium interactive sky map for exploring the stars and planets. 7, 8 [2]
SCOPE planetarium free online model of solar system and night sky. 7 [3]
Stellarium free open source planetarium for your computer. It shows a realistic sky in 3D, just like what you see with the naked eye, binoculars or a telescope. 7, 8 [4]

Notes
TYCHOS a revised model of our solar system. Its basic orbital configuration is based on the semi-Tychonian model as defined by Longomontanus in his Astronomia Danica (1622), a monumental work regarded as Tycho Brahe’s “testament”. Although the semi-Tychonic and the TYCHOS models are geometrically similar, they significantly differ in that the latter assigns an orbit to Earth – whereas the former considers Earth as a motionless (albeit diurnally-rotating) celestial body.

Galileo Galilei 16/17th Italian polymath, central figure in the transition from natural philosophy to modern science and transformation of the scientific Renaissance into a scientific revolution.

Ole Roemer 17th/18th Danish astronomer who in 1676 made the first quantitative measurements of the speed of light, persuaded the king to introduce the Gregorian calendar in Denmark-Norway — something Tycho Brahe had argued for in vain a hundred years earlier. 26 [WPR 14]
James Bradley 18th English astronomer and priest. Best known for two fundamental discoveries in astronomy, the aberration of light (1725–1728), and the nutation of the Earth's axis (1728–1748). Preface, 26, 34, Epilogue [T 9]
