See Jupiter and Mercury align in the sky and an asteroid flyby this weekend

The solar system’s largest and smallest planets will be in alignment this Friday.

아침에, Mercury and Jupiter will be in conjunction and appear just above the horizon, NASA에 따르면.
A conjunction is when two objects appear close together in the sky, but they can actually be millions of miles apart, according to Thomas Beatty, assistant astronomer at Steward Observatory at the University of Arizona in Tucson.
    It’s similar to a merry-go-round, 그는 말했다, with certain animals aligning as they circle around the center of the ride.
      To the naked eye, the planets will look like two bright stars, Beatty said.
        The best time to view the conjunction is in the early morning hours, but it might be difficult to see in the Northern Hemisphere, according to EarthSky. The views will be much better in the Southern Hemisphere due to Earth’s angle in the sky.

        Asteroid Apophis flyby

          An asteroid will make a flyby between Friday and Saturday, according to EarthSky. Apophis, an asteroid that spans over 1,312 피트, will be closest to the Earth — 위에 10 million miles from our planet or 44 times further than the moon — 3 월 5 ...에서 8:15 오후. 과.
          Unlike the conjunction, it will likely not be visible to the naked eye, Beatty said. Stargazers can view the asteroid flyby online for free through The Virtual Telescope Project 로마에서.
          When the asteroid was first discovered in 2004, scientists believed the asteroid had a small chance of hitting Earth in 2029, Beatty said.
          There was a one in 10,000 chance the asteroid was going to collide with Earth, but given the damage it would do, “one in 10,000 is sort of unacceptable from our standpoint of humanity,” 그는 말했다.
          운 좋게, the Apophis flyby in 2013 allowed scientists to gather better measurements and the new numbers show the chances are extremely low, Beatty added.
          He said the large asteroid will still be passing close in 2029 — 약 24,000 miles from Earth, according to EarthSkyand it will be easier to see in the sky compared to the 2021 flyby.

          Meteor showers

          There is a bit of a wait until the next meteor shower, the popular Lyrids in April. The Lyrids will peak on April 22 and will be best seen in the Northern Hemispherebut the moon will be 68% 완전한, 에 따르면 American Meteor Society.
          The Eta Aquariids follow soon after, peaking on May 5 when the moon is 38% 완전한. This shower is best seen in the southern tropics, but will still produce a medium shower for those north of the equator.
          The Milky Way is seen from the Glacier Point Trailside in Yosemite National Park, 캘리포니아.

          The Delta Aquariids are also best seen from the southern tropics and will peak between July 28 과 29 when the moon is 74% 완전한.
          재미있게, another meteor shower peaks on the same nightthe Alpha Capricornids. Although this is a much weaker shower, it has been known to produce some bright fireballs during the peak. And it will be visible for those on either side of the equator.
          The Perseid meteor shower, the most popular of the year, will peak between August 11 과 12 in the Northern Hemisphere when the moon is only 13% 완전한.
          Here is the meteor shower schedule for the rest of the year, 에 따르면 EarthSky’s meteor shower outlook.

          Solar and lunar eclipses

          올해, there will be two eclipses of the sun and two eclipses of the moonand three of these will be visible for some in North America, 에 따르면 The Old Farmer’s Almanac.
          A total eclipse of the moon will occur on May 26, best visible to those in western North America and Hawaii from 4:46 오전. ET to 9:51 오전. 과.
          An annular eclipse of the sun will happen on June 10, visible in northern and northeastern North America from 4:12 오전. ET to 9:11 오전. 과. The sun won’t be fully blocked by the moon, so be sure to wear eclipse glasses to safely view this event.
          십일월 19 will see a partial eclipse of the moon, and skywatchers in North America and Hawaii can view it between 1 오전. ET and 7:06 오전. 과.
          And the year ends with a total eclipse of the sun on December 4. It won’t be seen in North America, but those in the Falkland Islands, the southern tip of Africa, Antarctica and southeastern Australia will be able to spot it.

          Visible planets

          Skywatchers will have multiple opportunities to spot the planets in our sky during certain mornings and evenings throughout 2021, 에 따르면 Farmer’s Almanac planetary guide.
          It’s possible to see most of these with the naked eye, with the exception of distant Neptune, but binoculars or a telescope will provide the best view.
          Mercury will look like a bright star in the morning sky from February 28 3월까지 20, 유월 27 to July 16, 그리고 10 월 18 to November 1. It will shine in the night sky from May 3 5 월까지 24, 팔월 31 to September 21 11 월 29 12 월까지 31.
