This means that as it travels around the Earth it also moves up and down in its orbit. Since the Earth is around four times wider than the Moon, its shadow can darken the moon for up to five hours depending on conditions. Total lunar eclipses are much rarer from one particular location. When the moon is close to perigee, the closest point to Earth in its orbit, it makes the moon appear slightly larger than usual.

Top things to do. Courtesy Evan Zucker. Not quite 5 years later, another solar eclipse is coming to North America. On June 10, , the Moon will again pass directly between Earth and the Sun — but this time it will not quite completely cover the solar disk, instead turning it into a thin "ring of fire.
Combined with ongoing pandemic-related travel restrictions and less-than-optimal weather prospects, the remoteness of the path means that very few people will see this annular eclipse. But millions of Americans and Canadians northeast of a line running from central Alaska to central Alberta to central North Dakota to the border between Georgia and South Carolina will have a chance to see a picturesque partial solar eclipse at sunrise that morning.

There are a few different ways for lunar and solar eclipses to happen: A total eclipse of either the Moon or the Sun occurs when the Moon or Sun is entirely blocked out. During a total lunar eclipse , the Moon is completely obscured by the dark center of Earth's shadow called the umbra , giving the Moon a dark, reddish hue.
During a total solar eclipse , the Sun is completely obscured by the Moon, resulting in a brief period of awe-inspiring darkness.
A partial eclipse of either the Moon or the Sun occurs when only part of the Moon or Sun is obscured. An annular eclipse is a type of solar eclipse. Annular eclipses are similar to total solar eclipses where the Sun is completely obscured by the Moon , but in an annular eclipse, the Moon's apparent size is smaller than the Sun's, meaning that the Sun is not completely obscured.
This results in a very bright ring of light called an annulus. A penumbral eclipse is a type of lunar eclipse. Penumbral eclipses occur when the Moon enters only the faint outer edge of Earth's shadow called the penumbra , which causes the Moon to appear slightly darker than usual. The effect is so slight that a penumbral eclipse can be hard to recognize unless you know to look for it! There is also a phenomenon called a transit, which is similar to an eclipse, though not quite as visually stunning: A transit occurs when one celestial body passes between a larger celestial body and a third celestial body.
For example, when Mercury passes between the Sun and the Earth, this is called a transit of Mercury. Because Earth is the third planet from the Sun, we are able to observe transits of both Mercury and Venus. Sign up for our email newsletter by entering your email address. The amount of sun that the moon can block on a given eclipse encounter depends on where the moon is located in its elliptical orbit around the Earth. If the moon passes directly in front of the sun when it is near apogee, the point in its orbit where it is farthest from Earth, it will appear smaller than the sun in the sky.
You can see a complete list of the upcoming solar eclipses on NASA's eclipse website , which provides information about solar eclipses, including detailed maps of each eclipse path. Remember to start making plans for the next great American solar eclipse on April 8, The last solar eclipse of will be a total solar eclipse. It will bookend the year's solar eclipses by appearing over the pole opposite the June 10 event. The total solar eclipse on Dec.
Unlike the Northern Hemisphere, however, extreme latitudes in the Southern Hemisphere do not have a lot of land. Antarctica and its surrounding waters are the best places to view the eclipse, but some places on other continents will get at least a partial view.
The southernmost regions within Australia, New Zealand, Argentina and South Africa can catch a small shadow of the lunar disk moving over the sun, according to an interactive map from Time and Date.
