A comet larger than Everest should be visible to the naked eye as it approaches the sun over the next four weeks, experts say. 12P/Pons-Brooks visits Earth once every 71 years and could illuminate the sky during the April 8 solar eclipse. Space.com reported that it could be 5th-magnitude brightness upon its arrival, which would make it visible to the naked eye, just. Those in the Northern Hemisphere should plan a trip to see it before April 21, when it makes its closest approach to the sun. From then until the end of the year, it is expected to be visible to people in the Southern Hemisphere, according to Starwalk. 12P/Pons-Brooks made headlines when it became X100 brighter due to a rare flare that transformed the comet’s gas cloud into a horseshoe shape. Astronomers believe the flare-up occurred due to apparent volcanic activity on the surface of the comet. Experts urged those looking to catch a glimpse of it to bring binoculars and head to the countryside, away from city lights. Other factors to consider are the weather forecast, as an overcast night can ruin stargazing, and choosing a date closest to a new moon. A full moon can outshine other objects in the sky.
