A Super Lua ganha, por pouco, quando seu tamanho aparente é comparado ao do Sol nesta engenhosa foto composta.
Para fazê-la, a Lua Cheia de 6 de maio foi fotografada com a mesma câmera e telescópio usados para fazer imagens do Sol (com um denso filtro solar!) no dia seguinte.
É claro, em 6 de maio, a Lua estava no perigeu, o ponto mais próximo à Terra de sua órbita elíptica, o que a tornou a maior Lua Cheia de 2012.
Duas semanas depois, em 20 de maio, a Lua estará próxima ao apogeu, o ponto mais distante em sua órbita, logo, ela estará então próxima de seu menor tamanho aparente. Ela será também uma Lua escura naquela data.
E, para alguns, a Lua Nova será ainda surpreendentemente mais fácil de comparar ao Sol, porque em 20 de maio, a primeira eclipse solar de 2012 será visível de boa parte da Ásia, Pacífico, e América do Norte.
Ao longo de um trajeto entre 240 e 300 quilômetros de largura, a eclipse será anelar. Próxima ao apogeu, a silhueta menor da Lua caberá dentro do brilhante disco solar, formando um anel.
The Super Moon wins, by just a little, when
its apparent size is
compared to the Sun in this ingenious composite picture.
To make it, the Full Moon on May 6 was photographed with the same camera and telescope used to image the Sun (with a dense solar filter!) on the following day.
Of course, on May 6 the Moon was at perigee, the closest point to Earth in its eliptical orbit, making it the largest Full Moon of 2012.
Two weeks later, on May 20, the Moon will be near apogee, the most distant point in its orbit, so by then it will be nearly at its smallest apparent size. It will also be a dark New Moon on that date.
And for some the New Moon will be surprisingly easy to compare to the Sun, because on May 20 the first solar eclipse of 2012 will be visible from much of Asia, the Pacific, and North America.
Along a path 240 to 300 kilometers wide, the eclipse will be annular. Near apogee the smaller silhouetted Moon will fit just inside the bright solar disk.
