Stretching your arm in front of neighbors at the table disrupts their meals – and is a good way to accidentally upend the gravy boat. It is impolite to reach over someone to pick up food or other items. Diners should always ask for items to be passed along the table to them. In the same vein, diners should pass those items directly to the person who asked. Always scoop food, using the proper utensil, away from you. Always use serving utensils to serve yourself, not your personal silverware.

Dinnertime is also meeting time for most families, when everyone can discuss the day without smartphones and laptop screens getting in the way. Phones and other distracting items should not be used at the dining table. Reading at a table is permitted only at breakfast, unless the diner is alone. Urgent matters should be handled, after an apology, by stepping away from the table. Should a mobile telephone (or any other modern device) ring or if a text message is received, the diner should ignore the call. In exceptional cases where the diner feels the call may be of an urgent nature, they should ask to be excused, leave the room and take the call (or read the text message) out of earshot of the other diners. Placing a phone, keys, handbag or wallet on the dinner table is considered rude.

This rule goes back to medieval times, when diners eat shoulder-to-shoulder at narrow feasting tables with no elbow room to spare. Imagine a big old medieval feast given by a ruler or lord. Everybody and their mother wants to go to it, and boast about how they dined with such and such. Most of these feasts would have been served on long tables with benches instead of seats. People would pack in like sardines and there simply was no room to have your elbows on the table without jostling your neighbor and disrupting his ability to eat. Allowing your elbows to nudge the guy next to you and hit his arm while he’s bringing some food to his mouth would be obviously rude. As well, such accidents could cause quarrels, or even violence to break out.

NASA is planning to capture one. Its Asteroid Redirect Mission may attempt to nab an asteroid in a space probe’s “capture bag” and release the roving rock into lunar orbit. NASA hopes to begin landing astronauts on its captured asteroid by the mid-2020s.

Smaller asteroid impacts may be less catastrophic, but they can still cause significant damage. The space rock that exploded over Chelyabinsk, Russia, in 2013 was only 62 feet (19 m) wide, and it injured more than 1,200 people while damaging thousands of buildings as far as 58 miles (93 kilometers) away from the site of impact. NASA is starting to look for more of those smaller asteroids, now that most of the larger ones have already been cataloged.

There’s gold (and other precious metals) in those rocks! In fact, a company called Planetary Resources plans to send robot miners to the asteroid belt.

The asteroid belt probably contains millions of asteroids. Astronomers think that the asteroid belt is made up of material that was never able to form into a planet, or of the remains of a planet which broke apart a very long time ago. The asteroids in the asteroid belt come in a variety of sizes. Some are very small (less than a mile across), while others are quite large. The largest asteroid is called Ceres. It is about one-quarter the size of our moon. It is a dwarf planet.

Asteroids are roving rocks found in the asteroid belt between Mars and Jupiter.

A Meteor also known as shooting stars, meteors are places of rocks or ice that enter the Earth’s atmosphere. As much as 22,000,000 pounds (10,000,000 kg) of meteors burn harmlessly in the atmosphere each day.

Any piece of space debris that survives the fiery entry into Earth’s atmosphere is known as a meteorite once it touches down.
