A –

Absolute The apparent magnitude that a star

magnitude would have if it were observed from a

standard distance of 10 parsecs, or 32.6 light–

years. The absolute magnitude of the Sun is

4.8. at a distance of 10 parsecs, it would just

be visible on Earth on a clear moonless night

away from surface light.

Airy disk The apparent size of a star’s disk produced even by

a perfect optical system. Since the star can never

be focused perfectly, 84 per cent of the light will

concentrate into a single disk, and 16 per cent into a

system of surrounding rings.

Alt–Azimuth A telescope mounting using two

Mounting independent rotation axes allowing

movement of the instrument in Altitude

and Azimuth.

Altitude In astronomy, the altitude of a celestial object is

its Angular Distance above or below the celestial

horizon.

Aperture The diameter of a telescope’s primary lens or mirror;

the larger the aperture, the greater the telescope’s

light–gathering power.

Apparent A measure of the relative brightness of a

Magnitude star or other celestial object as perceived

by an observer on Earth.

Arc minute A unit of angular size equal to 1/60 of

a degree.

Arc second A unit of angular size equal to 1/3,600 of a degree (or

1/60 of an arc minute).

Asterism A small unocial grouping of stars in the

night sky.

Asteroid A small, rocky body that orbits a star.

Astrology The pseudoscientic belief that the positions of stars

and planets exert an inuence on human aairs;

astrology has nothing in common with astronomy.

Astronomical The distance between the Earth and the Sun.

unit (AU) It is equal to 149,597,900 km., usually

rounded o to 150,000,000 km.

Aurora The emission of light when charged particles from

the solar wind slams into and excites atoms and

molecules in a planet’s

upper atmosphere.

Azimuth The angular distance of an object eastwards along

the horizon, measured from due north, between

the astronomical meridian (the vertical line passing

through the center of the sky and the north and

south points on the horizon) and the vertical line

containing the celestial body whose position is to

be measured.

B –

Binary Stars Binary (Double) stars are pairs of stars that, because

of their mutual gravitational attraction, orbit around

a common center of mass. If a group of three or

more stars revolve around one another, it is called

a multiple system. It is believed that approximately

50 percent of all stars belong to binary or multiple

systems. Systems with individual components that

can be seen separately by a telescope are called

visual binaries or visual multiples. The nearest “star”

to our solar system, Alpha Centauri, is actually our

nearest example of a multiple star system. It consists

of three stars, two very similar to our Sun and one

dim, small, red star orbiting around one another.

C –

Celestial The projection of the Earth’s equator

Equator on to the celestial sphere. It divides the sky

into two equal hemispheres.
