The average distance from the Earth to the Sun is the unit of distance used for Solar System studies. It is called 1 Astronomical Unit (AU).n 1672 Cassini used the parallax of Mars to determine the distance to the sun. The result (140 million kilometers or 87 million miles) was within 10% of the correct answer.
An empty, cleaned wine bottle that I happened to have (okay, I drank the last few ounces of rich, sweet red wine I usually keep on hand that I use to make a marinade for my once-a-week steak) Battery-operated LED mini light set (15 lights), on sale at Walgreens a few weeks ago 3 for $10.
Use a chiller. A lot of wine shops have wine chillers that can quickly cool down a bottle of white wine. But they can chill a red, too. I'm not a huge fan because the temperature change is extreme and therefore potentially damaging to the wine, but it's an option. There it is, running past your campsite. Nature has provided a wonderful cooling system for that bottle of Pinot Noir you packed in for five miles.
