The smallest eccentric orbit of the planet means it does not pass through the Sun very often from the point of the Earth's vantage. This year, part of the 5.5-hour transit will be visible to many in North America starting at 7:36 a.m. ET. The eastern half of North America and the whole of South America will see the entire show, which will last until 1:04 p.m. ET. Africa, Europe, and western Asia will see this in the sunset Monday.
How do you find this? So, I would advise against walking straight into the Sun and even even more strongly against staring at the Sun through the binoculars or a telescope. Instead, it is best to use a telescope with a solar filter, by that would look like transit like a small black speck passing in front of the Sun, which would appear 194 times more larger than speck . If you do not have the tools, check if a local astronomy club will host a public viewing . The Virtual Telescope Project will have a look at on its website.
Transfers occur when the planets come between us and the Sun, which means only two planets can move: Venus and Mercury. Witnessing a transit is all a matter of timing. The Transits of Venus occur in pairs separated by 121.5 or 105.5 years, with eight years separating each journey; the next transit of Venus takes place in the year 2117. Mercury transfers are more frequent, as the planet travels in a smaller orbit around the Sun.
Mercury transfers have long been useful tools for scientists. Back in the 17th century astronomers observed Mercury transitions to try to determine the distance between Earth and Day using parallax – which observe the migration from two different places on Earth as written by National Radio Astronomy Observatory astronomer Brian Koberlein for Forbes. One team used transfers to indirectly calculate the impact of the tidal forces of the Earth's Moon. Recently, a team of scientists used a transit to see if it would make a noticeable decrease in the sun source of sunlight (without it). That knowledge was important to astronomers hoping to use the transit method to see exoplanets in distant stars.
Hope you have a chance to watch the transit on Monday. But remember, d who didn't look straight at Mr. Sun.
