Scientists working for a NASA-funded project at the University of Arizona said that a possible "mini moon" is currently orbiting the Earth. Kacper Wierzchos of the Catalina Sky Survey tweeted this week that an object, 2020 CD3, has been captured by Earth's gravitational pull, and is temporarily in orbit around the Earth. The object is not very large, only 6 to 11 feet, Wierzchos said, but he added it is still an extraordinary discovery. "it's a big deal as out of ~ 1 million known asteroids, this is just the second asteroid known to orbit Earth (after 2006 RH120, which was also discovered by the Catalina Sky Survey)," he tweeted. 2020 CD3 began orbiting the Earth three years ago. Elon Musk, the head of Tesla, jokingly tweeted, "It’s not mine." Tesla sent a Roadster into space in 2018. BIG NEWS (thread 1/3).

Spring is just days away! That means a lot of people are gearing up to “spring clean” their homes. But it’s also a great time to “spring clean” your health!One of the best parts about spring: more sun shine. "Having sun exposure before noon is scientifically proven to help you with mood and sleep,” says Dr. Kate Johnson, a family medical practitioner. Dr. Johnson says sunblock is a must for your skincare regimen, and the higher the SPF the better. "Even though we can get vitamin D from the sun, we can take that in a supplement to protect our skin," she says. Come spring, there are plenty of new fruits and vegetables in season, including apricots, asparagus, strawberries and artichokes. Unfortunately, when nature is in full bloom, that means allergies are, too. So, before they strike, stock up on nasal sprays. "You want to hop on those right now,” Dr. Johnson says. “I recommend dosing them at bedtime." When taking care of your health this spring, it’s a good time to ditch the “I can’t exercise” mentality. "If you are not an avid exerciser currently, I recommend starting with walking,” Dr. Johnson recommends. “[It’s] a fantastic way to go, and I like to tell my patients to start with 5 minutes is a great start, and we can build as we go." Remember, no matter the season, sleep is key! Don't let anything come between you and rest. Dr. Johnson recommends putting you phone down before sleep, as it can interfere with falling asleep. 1466
