I'm pretty sure a planet with that much mass cannot exist according to the laws of physics.

Scientists estimate that several dozen asteroids in the 6–12 m (20–39 ft) size range fly by Earth at a distance closer than the moon each year, but only a fraction of these are actually detected, which means having some form of "control" over what they are in principle impossible.

I had an app called 'Asteroid Alert' and there was more than just a few alerts of objects flying closer than the moon is to earth. First time it alerted my eyes got real big, I was like "damn that's close!"

You said "you had", does that mean it no longer exists, you have a link? ... Such a small sweet app could give a little excitement ... as the rest of life gives. Especially then with regard to what you experienced yourself.

A Nasa probe sent to collect rock from an asteroid several hundred million kilometres from Earth is back on track after some technical concerns.

Officials behind the Osiris-Rex probe, which landed on Bennu earlier this week, were worried https://www.bbc.co.uk/news/science-environment-54672691 This meant that samples were spilling out from the craft.

But now the space agency says the rock samples have been safely sealed and the probe is ready to return to Earth.

If you want a cool app that you can have on your phone where you can have a guide to the night sky and see everything there, you should get the Skyguide app, amazing!

I love it, very nicely mapped.

P.S. I am not a bot or anything even though it may sound like it.

Sky Map by Google and Stellarium are also excellent apps. Stellarium is also available for free for desktop.
