What dates do apogee and perigee occur?
This year’s farthest apogee comes on May 11, 2021 (252,595 miles or 406,512 km), and the closest perigee occurs on December 4, 2021 (221,702 miles or 356,794 km).
How often does perigee and apogee occur?
During every 27-day orbit around Earth, the Moon reaches both its perigee, about 226,000 miles (363,300 km) from Earth, and its farthest point, or apogee, about 251,000 miles (405,500 km) from Earth.
What did the moon look like on June 11 2012?
The current moon phase for June 11th, 2012 is the Last Quarter phase. On this day, the moon is 20.91 days old and 54.13% illuminated with a tilt of -59.966°. The approximate distance from Earth to the moon is 392,363.57 km and the moon sign is Pisces.
How do you calculate apogee and perigee?
The apogee for an elliptical path is A=a(e+1). The perigee for an elliptical path is P=a(1−e).
What phase was the Moon in August 12 2000?
On this day the Moon was in a Waxing Gibbous phase. This phase is when the moon is more than 50% illuminated but not yet a Full Moon. The phase lasts about 7 days with the moon becoming more illuminated each day until the Full Moon.
What is the day in November when the Moon reaches apogee 2021?
November 20, 2021
The Moon reaches apogee tonight when the Earth and Moon will be separated by 406,279 km. Over a period of 27.5 days, the Moon reaches its apsides. Apsides represent the close and far points in an objects orbit.
What did the Moon look like on June 7 2012?
The current moon phase for June 7th, 2012 is the Waning Gibbous phase. On this day, the moon is 16.78 days old and 91.75% illuminated with a tilt of -63.595°. The approximate distance from Earth to the moon is 368,031.65 km and the moon sign is Capricorn. The Moon phase for June 7th, 2012 is a Waning Gibbous phase.
What did the Moon look like on June 6 2012?
Waning Gibbous 94% illuminated Waning Gibbous is the lunar phase on 6 June 2012, Wednesday . Seen from Earth, illuminated fraction of the Moon surface is 94% and getting smaller. The 17 days old Moon is in ♑ Capricorn.
What is apogee and perigee?
The Moon’s orbit around Earth is elliptical. The point of the orbit closest to Earth is called perigee, while the point farthest from Earth is known as apogee.
WHAT IS A in apogee formula?
How do we calculate them? Apogee means the furthest distance the Moon or a satellite gets from Earth in its orbit. A=a(1+e) Perigee means the closest distance the Moon or a satellite gets to Earth in its orbit.
What phase was the Moon in August 21 2000?
On this day the Moon was in a Waning Gibbous Phase. This is the first phase after the Full Moon occurs. It lasts roughly 7 days with the Moon’s illumination growing smaller each day until the Moon becomes a Last Quarter Moon with an illumination of 50%.
What did the Moon look like on August 12 1999?
On this day the Moon was in a Waxing Crescent Phase. A Waxing Crescent is the first Phase after the New Moon and is a great time to see the features of the moon’s surface. During this phase the Moon can be seen in the wester sky after the sun dips below the horizon at sunset.
How accurate are perigee and apogee distances?
Perigee and apogee distances are usually accurate to within a few kilometres compared to values calculated with the definitive ELP 2000-82 theory of the lunar orbit; the maximum error over the years 1977 through 2022 is 12 km in perigee distance and 6 km at apogee.
What do the numbers on the Moon’s perigee and apogee mean?
The Moon’s geocentric distance and apparent diameter (arc-minute) are given for both perigee and apogee. The ‘m’ and ‘M’ after some distances indicate the minimum and maximum values, respectively, each year. For conversion from Greenwich Mean Time to other time zones, see Time Zones and Universal Time .
How do perigee and apogee affect tides?
Perigee and apogee also affect the tides. During the final quarter of the 20th century, the Moon was as close to Earth as 216,500 miles (surface to surface) at its most extreme perigee and as far away as 247,700 miles at its most extreme apogee. At perigee, tidal ranges are increased; at apogee, they are decreased.
