Delta Microscopii

Δ Microscopii, Latinised as Delta Microscopii, is a faint, orange hued binary star system in the constellation Microscopium, marking the eyepiece end of the "microscope". It is just visible to the naked eye with an apparent visual magnitude of +5.68. Based upon an annual parallax shift of 10.82 mas as seen from the Earth, it is 300 light years from the Sun. At that distance, the visual magnitude is diminished by an extinction factor of 0.142 due to interstellar dust. This is a single-lined spectroscopic binary with an orbital period of 4.4 years and an eccentricity of 0.2. The visible component is an evolved K-type giant star with a stellar classification of K0/1 III, it is on the horizontal branch and thus is generating energy through helium fusion at its core. Delta Microscopii has nearly twice the mass of the Sun and has expanded to 11 times the Sun's radius; the star is radiating 57 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,805 K

Esslingen railway station

Esslingen is a railway station in the Swiss canton of Zürich and the municipality of Egg. It is the outer terminus of the Forchbahn from the city of Zürich, operated as Zürich S-Bahn service S18; the station is operated by the Forchbahn, has three terminal platforms and a bus interchange located under an overall roof. It serves the village of Esslingen; the Forchbahn was opened as a roadside electric tramway, has been progressively upgraded into a modern electric railway. Between the Forchbahn's opening in 1912 and 1949, it connected at Esslingen with the Uster–Oetwil tramway, another similar roadside tramway that closed in 1949; the stop both lines shared was situated to the east of the existing station near the junction of Löwenstrasse and Usterstrasse, is still marked by the presence of the Restaurant Bahnhof. The line's terminus was relocated to its current site in 1995. Today the station provides interchange with buses on route 842 of the Verkehrsbetriebe Zürichsee und Oberland, which links Uster and Oetwil am See and replaces the UOeB.
