Mercury is the smallest planet in the Solar System and the one closest to the Sun, with an orbital period of about 88 Earth days, which is much faster than any other planet in the Solar System. Seen from Earth, it appears to move around its orbit in about 116 days. It has no known natural satellites. It is named after the Roman deity Mercury, the messenger to the gods.
Partly because it has almost no atmosphere to retain heat, Mercury's surface temperature varies diurnally more than any other planet in the Solar System, ranging from 100 K (−173 °C; −280 °F) at night to 700 K (427 °C; 800 °F) during the day in some equatorial regions. The poles are constantly below 180 K (−93 °C; −136 °F). Mercury's axis has the smallest tilt of any of the Solar System's planets (about 1⁄30 of a degree). However, Mercury's orbital eccentricity is the largest of all known planets in the Solar System. At aphelion, Mercury is about 1.5 times as far from the Sun as it is at perihelion. Mercury's surface is heavily cratered and similar in appearance to the Moon, indicating that it has been geologically inactive for billions of years.

Mariner 10 was an American robotic space probe launched by NASA on November 3, 1973, to fly by the planets Mercury and Venus.
Mariner 10 was launched approximately two years after Mariner 9 and was the last spacecraft in the Mariner program (Mariner 11 and 12 were allocated to the Voyager program and redesignated Voyager 1 and Voyager 2).
The mission objectives were to measure Mercury's environment, atmosphere, surface, and body characteristics and to make similar investigations of Venus. Secondary objectives were to perform experiments in the interplanetary medium and to obtain experience with a dual-planet gravity assist mission. Mariner 10's science team was led by Bruce C. Murray at the Jet Propulsion Laboratory.
Mariner 10 was the first spacecraft to make use of an interplanetary gravitational slingshot maneuver, using Venus to bend its flight path and bring its perihelion down to the level of Mercury's orbit. This maneuver, inspired by the orbital mechanics calculations of the Italian scientist Giuseppe Colombo, put the spacecraft into an orbit that repeatedly brought it back to Mercury. Mariner 10 used the solar radiation pressure on its solar panels and its high-gain antenna as a means of attitude control during flight, the first spacecraft to use active solar pressure control.

Johns Hopkins (May 19, 1795 – December 24, 1873) was an American entrepreneur, abolitionist and philanthropist of 19th-century Baltimore, Maryland.
His bequests founded numerous institutions bearing his name, most notably Johns Hopkins Hospital, and Johns Hopkins University (including its academic divisions such as Johns Hopkins School of Nursing, Johns Hopkins School of Medicine, Johns Hopkins Carey Business School, and Johns Hopkins Bloomberg School of Public Health).
A biography entitled Johns Hopkins: A Silhouette written by his cousin, Helen Hopkins Thom, was published in 1929 by the Johns Hopkins University Press.
Johns Hopkins was born on May 19, 1795. He was one of eleven children born to Samuel Hopkins (1759–1814) of Crofton, Maryland, and Hannah Janney (1774–1864), of Loudoun County, Virginia. His home was Whitehall, a 500-acre (two km²) tobacco plantation in Anne Arundel County. His first name was inherited from his grandfather Johns Hopkins who received his first name when his mother Margaret Johns married Gerard Hopkins.

WASHINGTON — Our solar system's smallest planet will be visible on Monday, May 9 as it passes between Earth and the sun, in a rare spectacle that only occurs a few times a century. Mercury will take about seven and a half hours to move across the sun beginning from 7:12 a.m. EST until around 2:42 p.m. EST. Mercury, which is about three times smaller than Earth, will be just 1/158 the width of the sun's disk, so its movement across the sun is only visible with high-powered lenses. While the Earth takes 365 days to orbit the sun, Mercury takes only 88 days to make the journey. This means that Mercury passes between Earth and the sun three times a year, or about once every four months. However, as Mercury's orbit is inclined seven degrees to the plane of Earth's orbit, it's rare for the thr...
