"As well as offering a change of seasons the much acre Knox's also brought with a circle superman that happened just four hours after the moment of equinox. The closest since March and the two thousand and it will be another eleven years twenty thirty before the two events will gain be less than a day apart. Well, just think of that we now closer to twenty thirty what want to the thousand a by the way, this was also the third and final superman for twenty nine chain. The term ship moon was invented back in nineteen seventy nine by an astrology not on astronomy for those unfamiliar with the difference between the two and astronomers a person to study space in the cosmos, using the scientific method to learn about the universe and astrologer is a person uses inaccurate positions. Constellations planets and other celestial bodies at different times in order to tell people about the character would have predict the future has never ever ever ever ever ever. Been any scientific evidence. Supporting any of the claims made by strategy and its success depends exclusively on the Gulf ability of people now back to the science on average the moon orbits about three hundred eighty four thousand four hundred kilometers from earth. But the moon's orbit around the earth isn't a perfect circle. It's slightly elliptical. Meaning one part of the orbit will be closer to the earth. Bet. Three hundred fifty seven thousand kilometers is parody. And the other part of the oil, but will be further away around four hundred and six thousand kilometres apogee, the differences about five percent closer or further away on average the exact distances of perishing apogee, also very other factors such as whether the lunar orbits long axes pointed towards the sun. Also, the moon's Ogle extremes a greatest between November and February when the earth, oh, but places the planet and its moon close into the sun, you say earth orbit itself is also elliptical by that two percent. And they will the sun's gravitational influence is greatest during these months, technically. These would be Jane full moons but trend to its east terms like what use the description of super moon to describe any Newell full moon with a ninety degrees of parody syncing opportunity. Nassar's now adopted this term as a means of educating the public about astronomy twenty nineteen will be an excellent year to look to the sky and enjoy the spectacular view of earth's nearest neighbor. The moon fifty years ago, we witnessed one of humankind's most, remarkable achievements. When we first step foot on the dusty surface of the moon. All for man. By ugly. As NASA continue celebrating the fiftieth anniversary of the Apollo program. The year is opening with a number of opportunities to marvel at earth's original satellite, three super moons, and a total lunar eclipse in the span of three months. So what is it that makes a super moon super start with size? The moon orbits around the earth in a slightly oval shape at its furthest point away from us known as the apogee it's about two hundred fifty thousand miles or four hundred thousand kilometers from earth when it's closest to us. It's parody. The moon is about two hundred twenty thousand miles or three hundred fifty thousand kilometers away when the moon is full at or near its parody. It is considered a super moon and can appear up to fourteen percent larger and thirty percent brighter than it apogee. Those distances however are changing as the moon is slowly. Shifting away from earth how slowly approximately two inches or five centimeters annually a billion years from now the moon will take about thirty one and a half days to orbit the earth. Instead of today's twenty seven point three days. In the meantime, this year's first superman of the year occurred on January twenty first and also featured a total eclipse, the second occurred on February nineteenth and sky watchers. Another chance on March twenty first well, super moons. Total lunar eclipses are marvels to behold. A question rises fifty years after humankind's first steps on the moon. Does it hold anymore secrets for NASA? Scientists Noah petro project, scientists for the lunar reconnaissance orbiter or El aro at nestles Goddard Space Flight center says there are many unanswered questions about the moon. For example, we are still attempting to understand how the moon evolved to its current state. The moon has occupied space near earth for its entire four and a half billion year history. Keeping record of the impacts that have scarred on its surface over time. This record of anxious impacts is largely erased from the earth due to win water in plate tectonics analysis of Apollo samples shows that there was a period of intense impact cratering on the moon early in the history of the solar system and therefore on the earlier as well observations from L our show now in its ninth year of orbiting the moon or helping us piece together this history people say shoulda moons, especially big in brunt compare to regular full moons, but will a can be around fourteen percent lodge and thirty percent broader, you really wouldn't notice the difference unless someone told you and even then any size difference perceptions. You do have will be more likely GTO imagination in reality, you'd really need proper non-legal equipment to Mitch the difference. And remember the full moon always looks lodge and Bryant when it's near the horizon and a fake none as men allusion. The other important point member is. That Superman's not all that uncommon. They usually current groups of three roughly about every thirteen months in eighteen days. In other words, roughly every fourteenth full moon will be superman now one consequence of superman that should be noticeable involves ocean tides many factors influence title heights at a given location that they usually highest something that a spring tides during full moons or new moons when the earth sun and moon are all aligned so a parody moon being big plus than average should result in a slightly higher high tide."
