A Christmas asteroid is approaching Earth. What is it and how scared should you be?

Amateur astronomers are in for a Christmas treat!While launching its new asteroid toolkit this holiday season, the European Space Agency (ESA) has enlisted the help of space enthusiasts in finding a space rock around the size of the Statue of Liberty that is rapidly approaching Earth.The space rock known as “2015 RN35”, which was first discovered on 9 September, 2015, is travelling at a blazing 21,276 km per hour.According to ESA, the asteroid will make its closest approach towards Earth on 15 December at 1.42 pm IST.The asteroid will be 686,000 kilometres away from the Earth.Richard Moissl, ESA Head of Planetary Defence said in a blog post, “Like many middle-sized space rocks out there, we just don’t know that much about it. This middle-sized asteroid, 60-140 metres in diameter, will fly close to Earth on 15 December, becoming visible to amateur astronomers around the globe. Join the challenge to spot it with #ESAChristmasAsteroid.”Also read: India’s first private space launchpad, Agnikul, is set to give the aerospace industry a major boostWhat are asteroids made up of?Space rocks or asteroids are small and rocky pieces of minerals that were left over when the solar system formed approximately 4.6 billion years ago.

Since they are smaller than planets, they are often referred to as minor planets.

The NASA Joint Propulsion Laboratory believes that an asteroid is “considered to be close to Earth if it is less than 1.3 times the distance between Earth and the Sun, which is approximately 93 million miles away.”How to spot the Christmas asteroid?Spotting the asteroid can be a challenge.According to the ESA, the space rock will not shine brightly in the sky.The space rock has a visual magnitude below 14, which is comparable to that of Pluto.“2015 RN35 will not shine bright in the skies like the star of Bethlehem did millennia ago. So why is 2015 RN35 interesting? Firstly, there’s not a single asteroid out there that isn’t. Near-Earth asteroids fascinate ESA’s Planetary Defence Office in particular because they give us key insights into the composition and trajectory of potentially hazardous objects,” ESA said.[caption id="attachment_11800741" align="alignnone" width="640"]

The Christmas asteroid will make a safe approach to Earth on 15th December.

Near-Earth asteroids like this one are important as they offer key insights into the composition and trajectory of potentially hazardous objects.”Also read: Mysterious US spacecraft returns after 908 days, speculation grows over secret missionWill it hit Earth?No.The agency has said there is zero chance that the asteroid will strike the Earth in the next 100 years.With inputs from agenciesRead all the Latest News, Trending News, Cricket News, Bollywood News,India News and Entertainment News here.
