Pluto has a moderately eccentric and inclined orbit, ranging from 30 to 49 astronomical units (4.5 to 7.3 billion kilometres; 2.8 to 4.6 billion miles) from the Sun. Light from the Sun takes 5.5 hours to reach Pluto at its orbital distance of 39.5 AU (5.91 billion km; 3.67 billion mi).
A large, strong tornado impacted a farm, destroying two barns and throwing the debris more than 0.5 miles (0.80 km) away. In addition, it ripped the entire roof off a one-story home, with 2 by 4 feet (0.61 by 1.22 m) boards driven into a field 250 yards (230 m) away.
The semi-major axis of the geocentric lunar orbit, called the lunar distance, is approximately 400,000 km (250,000 miles or 1.28 light-seconds), comparable to going around Earth 9.5 times. [177] The Moon makes a complete orbit around Earth with respect to the fixed stars, its sidereal period, about once every 27.3 days.
In November 2013, astronomers reported, based on Kepler space mission data, that there could be as many as 40 billion Earth-sized planets orbiting in the habitable zones of Sun-like stars and red dwarfs within the Milky Way. [166] [167] [168] 11 billion of these estimated planets may be orbiting Sun-like stars. [169]
The lunar distance is on average approximately 385,000 km (239,000 mi), or 1.28 light-seconds; this is roughly 30 times Earth's diameter or 9.5 times Earth's circumference. Around 389 lunar distances make up an AU astronomical unit (roughly the distance from Earth to the Sun). Lunar distance is commonly used to express the distance to near ...

It continued to strengthen until it reached its peak intensity as a major Category 3 hurricane with 115-mile-per-hour (185 km/h) sustained winds and a minimum pressure of 970 mbar (28.64 inHg) as it made landfall at Cocodrie, Louisiana, that evening. Zeta continued on through Mississippi and parts of Alabama with hurricane-force winds.
