One of the more unusual Twitter accounts I follow is lowflyingrocks. This account, set up by Tom Taylor, tweets every time when non-tiny objects pass within 0.2 astronomical units (about 18.6 million miles or 31 million kilometers) of Earth. The twitter account gets information from a NASA database for this purpose.
Many of these objects could do some damage if they were strike Earth, so every time I see a tweet saying an object has missed us, I realize that no matter how bad the day has been, it could have been much worse
