3122 Florence

3122 Florence is a stony trinary asteroid of the Amor group. It is classified as near-Earth object and potentially hazardous asteroid. It measures approximately 5 kilometers in diameter. It orbits the Sun at a distance of 1.0–2.5 AU once every 2 years and 4 months (859 days); the orbit has an eccentricity of 0.42 and an inclination of 22° with respect to the ecliptic. Florence has two moons.

Florence was discovered on 2 March 1981 by American astronomer Schelte J. "Bobby" Bus at Siding Spring Observatory. Its provisional designation was 1981 ET3. It was named in honor of Florence Nightingale, the founder of modern nursing; the naming citation was published on 6 April, 1993 (M.P.C. 21955).

Florence is classified as a potentially hazardous object because its minimum orbit intersection distance (MOID ≤ 0.05 AU) indicates that it has the potential to make close approaches to the Earth, and because measurements of its absolute magnitude (H ≤ 22) suggest that it is large enough to create serious damage were it to impact.

Caterpillar 3126

The Caterpillar 3126 is a turbocharged 7.2L inline 6-cylinder diesel engine manufactured by Caterpillar and first introduced in 1997; it was the first electronic mid-range diesel engine that Caterpillar produced. It is the successor to the Caterpillar 3116 engine and was replaced by the Caterpillar C7 engine in 2003. It is a medium-duty engine and has been used in dump trucks, long haul trucks, ambulances, buses, RVs, boats, cranes, fire trucks, and more. In 1998, Caterpillar released an improved version, the 3128B; in 2002, the 3126E was released; though these improved versions only affected engine electronics, not the actual engine design. Caterpillar launched a three-tier system of overhaul kits for the 3126 and its C7 successor in 2011.

It was rated for multiple power applications from 170HP to 330HP.

The Eight Burst Nebula (NGC 3132)

It's the dim star, not the bright one, near the center of NGC 3132 that created this odd but beautiful planetary nebula. Nicknamed the Eight-Burst Nebula and the Southern Ring Nebula, the glowing gas originated in the outer layers of a star like our Sun. In this representative color picture, the hot blue pool of light seen surrounding this binary system is energized by the hot surface of the faint star. Although photographed to explore unusual symmetries, it's the asymmetries that help make this planetary nebula so intriguing. Neither the unusual shape of the surrounding cooler shell nor the structure and placements of the cool filamentary dust lanes running across NGC 3132 are well understood.
