The Minor Planet Centre has just announced that the Earth has been orbited by a second moon for the past three years or so. Yes, really. Here's everything you need to know.
So, Earth has a new moon. While excitement about the discovery is growing, it is important to keep in mind that this moon isn’t as impressive as our main satellite. It is extremely faint – it is estimated to be only between one and six metres across – and won’t be with us for much longer.
Subsequent observations enabled its orbit to be calculated, and at 22:53 Universal Time (UT) on February 25, the Minor Planet Center announced the discovery, designating it as 2020 CD₃ and confirming that it is temporarily bound to the Earth.
The object 2020 CD₃ is essentially just a tiny member of a class of asteroids whose orbits cross the Earth’s orbit. Occasionally, they come near or collide with the Earth, but in this case a collision would not have been a catastrophe for us because 2020 CD₃ is so small that it would have broken up in the atmosphere before reaching the ground.
Instead of colliding with our planet, however, the initial approach of 2020 CD₃ towards the Earth meant that it was captured into orbit at a somewhat greater distance than our much larger, permanent moon.
Most people know not to feed chocolate to dogs. But did you know many other common foods in your fridge and larder are equally poisonous to canines? Everything from orange peel to toothpaste has the potential to make your dog seriously ill — in the wrong circumstances, it could even kill them. With that in mind, here are 25 everyday foodstuffs and other consumables that you should avoid feeding to your dog at all costs.
If something is free—especially if it’s a complicated something, or something you’d probably have to pay for otherwise—the familiar saying is often true: You’re the product. It’s one of the reasons you’re always being advertised to across the web. Search engines, email services, messaging platforms, or other apps and services you fancy cost money, and companies have to recoup that somehow (and profit).
