When Will Mars Be This Close Again
Mars is at its closest to Earth until 2035. Hither's how to come across it.
Wait up! Mars is at its closest to Globe until 2035 today (Oct. 6), making it a perfect time to see the Ruby-red Planet with your own optics.
Today at 10:xviii a.m. EDT (1418 GMT), Mars swoops within 38,568,816 miles (62,070,493 kilometers) of Globe, making a shine close approach. This will exist the closest the Ruby-red Planet will come up to World for the next15 years, or until September, 2035, co-ordinate to Earthsky.org.
The planet is visible loftier in the eastern sky. It appears as a stunning reddish light, weather permitting.
"October is a great time for viewing Mars, as the planet is visible all night right at present, and reaches its highest point in the heaven around midnight," NASA wrote in a skywatching guide.

World and Mars travel around the sun in elliptical orbits, orbiting in the same management but at different speeds and at different distances from our star. Every 780 days, or about every 2 years, Mars and Globe line upwardly and are the closest to each other during this time period. Today, the pair of planets volition make this close approach.
This close approach comes shortly before Mars' opposition, which is when Globe comes between the lord's day and Mars and they all line upwardly, on Oct. 13. Now, it might seem as though the closest approach should exist when the planets are lined upwardly in opposition, but it is not because they have elliptical orbits.
"If both the World and Mars circled the sun in perfect circles, and on the same exact airplane, the distance between Earth and Mars would always be least on the twenty-four hours of Mars' opposition. Just nosotros don't live in such a symmetrical universe," according to Earthsky.org.
The final shut arroyo betwixt the planets in 2018 was even closer than this one, but in 2003, the pair made a historic approach. In 2003, Mars came closer to Earth than it had in about sixty,000 years, 34.65 million miles (55.76 1000000 km), according to Earthsky.org. The Red Planet won't come closer than this until Aug. 28, 2287 when it volition exist 34.60 million miles (55.69 million km) from Earth, according to Earthsky.org.
While skywatching hoaxes keep to alive on on the internet, do note that, while Mars volition be especially shut today, it will not be as big (or even "nearly equally big") as the moon in the sky. While Mars will shine extra bright this October, its close arroyo isn't fifty-fifty remotely close plenty to announced as large as the moon. In fact, there is never an occasion where Mars looks as large as the moon in the sky.
While you're looking up at the sky to spot Mars, go along your optics peeled for satellites as this calendar week is World Space Week, which this twelvemonth celebrates satellite engineering science. You can find out how to spot satellites via the Earth Space Calendar week website here.
