For a comparison, Mercury’s size is about a third of Earth, and Earth has a density of 5.51 g/cm³.Despite being the smallest terrestrial planet from the Solar System, and in fact the smallest of all the planets, it is the second densest planet in the Solar System, with a density of 5.43 g/cm³.It orbits around the Sun with a speed of about 29 miles or 47 kilometers per second.This also makes one year on Mercury the equivalent of 88 Earth days, the shortest year of any planet. Despite its closeness to the Sun, it is not the hottest planet, that title belongs to Venus but Mercury is the fastest planet, completing a trip around the Sun in 88 Earth days.It takes sunlight 3.2 minutes to travel from the Sun to Mercury. Mercury is the closest planet to the Sun at a distance of 57.91 million kilometers / 35.98 miles or 0.4 AU away.Mercury was named after the Roman messenger god, because of its fast movements around the Sun.This paradoxically makes Mercury the closest planet to Earth, a plurality of the time. Venus spends most of its time away from Earth.In Venus’s case, it was also mistakenly believed to be two different things. In ancient times, Mercury was taught as being two different objects in the sky: The Mourning Star and The Evening Star.Galileo’s crude telescope didn’t manage to capture Mercury’s phases, this would be observed later by astronomer Giovanni Zupi in 1639, and thus he discovered that the planet had similar phases like Venus and the Moon.However, it was first observed with the help of a telescope in early 17 th century, by Galileo Galilei. Since Mercury can be seen without the need of a telescope, many ancient civilizations saw the planet, and as such it is impossible to determine who discovered it first.Army plans integrated battlefield surveillance centres.India slams Pakistan: Terror victims, perpetrators can’t sit together.

For the next three days (May 29 to 31), peak wind speed is likely to be 18 km/h causing moderate dispersion and AQI is likely to be within ‘moderate’ or ‘lower end of poor’. “Dust (size of more than 2.5 micrometer) contributes to 66% to PM10. System of Air Quality and Weather Forecasting And Research, a forecasting body under the union ministry of earth sciences, said PM10 was the lead pollutant. Delhi’s air quality, meanwhile, continued to remain in the ‘poor’ category with an overall air quality index (AQI) of 210. Though the temperature has been rising gradually, no sudden increase in temperature is expected in the next few days,” said the official. “The capital got respite from heatwave conditions last week as rain had helped in bringing down the mercury level on May 22. Safdarjung has reported 9 heatwave days in April and four in May. However, heatwave conditions are not predicted for the next six days.” Parts of Delhi have witnessed over 20 heatwave days since May-end. Strong surface winds at the speed of 25-35 kmph are expected on June 1 and 2. It may touch 42 degrees Celsius on May 31. A Met official said, “The maximum temperature is likely to rise further to 41 degrees Celsius on Sunday.
