56 Aquilae is a single[7] star in the equatorial constellation of Aquila. 56 Aquilae is its Flamsteed designation. Its apparent visual magnitude is 5.79,[2] meaning it is barely visible to the naked eye as a dim, orange-hued point of light, under ideal viewing conditions. The star is located at a distance of around 580 light years away from the Sun, based on parallax.[1] It is moving closer to the Earth with a heliocentric radial velocity of −50 km/s,[5] and is predicted to come as near as 222 light-years in around 3.3 million years.

This is an aging giant star with a stellar classification of K5 III,[3] having exhausted the supply of hydrogen at its core and expanded to 42[1] times the Sun's radius. It is radiating 391[1] times the luminosity of the Sun from its photosphere at an effective temperature of 3,972 K.[1] 56 Aquilae is a double star,[8] but it does not appear to be a binary star system.[7] It is one of the double stars profiled in Admiral William Henry Smyth's 1864 work, Sidereal Chromatics.

Members of the New South Wales Legislative Council, 1991–1995

Members of the New South Wales Legislative Council who served in the 50th Parliament were affected by the 1991 referendum which reduced the number of members and reduced their term from three terms of the Legislative Assembly to two terms, meaning the maximum term was eight years. The Council consisted of 42 members, 12 elected in 1984, 15 elected in 1988 and 15 elected in 1991. Half of the council would face re-election in 1995 and half did not face re-election until 1999.[1][2&...
