Facts About Time

Introduction

Time is one of those things we take for granted. We know that it passes, but we don't really think about what that means or how it works. So here are some facts about time that may help clear up some confusion around this topic:

Time is a concept that many people have trouble grasping.

Time is a concept that many people have trouble grasping. Time is not something that can be seen, heard or felt; it's not tangible and it's not visible. Because of this, we have difficulty understanding time's role in our lives and the world around us.

Time has many different meanings depending on where you are: what year? What day of week? How long does it take for something to happen? How long from now until then will it take for that thing to happen? And what exactly happens when something doesn't happen within its expected timeline?

Time is measured by using the movement of the Earth around its own axis.

Time is measured by the movement of the Earth around its own axis. The Earth spins on its axis, causing day and night. At this rate, days are longer in winter than they are in summer.

When you think about how long it takes for our planet to spin around once every 24 hours, it may seem like a simple thing--but there's more going on than meets the eye! The reason for this is that our planet isn't exactly perfect in shape: It's slightly tilted at an angle called 23 degrees (about 1/2 degree less than what scientists would expect). That slight tilt means that we experience seasons: Winter lasts longer than summer does because when you're standing still on Earth looking up at an object directly overhead such as a mountain peak or horizon line with no obstructions between them (like trees), then at any given point during daylight hours all parts of your body will be facing toward either directly north or south depending where they're located on earth's surface while also facing eastward toward sunrise due north so long as there aren't any mountains blocking those directions; however if there were mountains blocking these views then only partials would be visible instead

On average, Earth travels around the Sun once every 365 days or so.

On average, Earth travels around the Sun once every 365 days or so. This is called an "orbital" period.

Earth's orbit is elliptical: it takes about one year to go around once and then goes back to where it started (1 AU = 150 million km). The reason for this is that we're not in a perfect circle; there are other planets pulling on us and changing our path slightly.

The Earth-Sun distance varies from about 100 million km at perihelion (closest point) to about 150 million km at aphelion (furthest point).

Our solar system is one of billions in our galaxy that make up the Milky Way.

The Milky Way is a spiral galaxy that contains 100 billion stars. It's estimated to be about 100,000 light years across and approximately 25,000 light years in diameter.

The universe is huge, but there are many galaxies (which are collections of stars) throughout it. The Milky Way is one of billions in our galaxy; there are billions more out there!

The Milky Way has about 100 billion stars, most of which are too dim to be seen with the naked eye.

The Milky Way has about 100 billion stars, most of which are too dim to be seen with the naked eye. The Sun is a star in our own galaxy, one of more than 100 billion other similar galaxies in the observable universe.

The Milky Way is a spiral galaxy: it rotates around its center at about 220 km/h (136 mph). It's about 100,000 light years across and 10,000 light years thick!

There are about 200 billion planets in our galaxy alone; many more could be out there in other galaxies as well.

There are about 200 billion planets in our galaxy alone; many more could be out there in other galaxies as well. This is a big number, but it only represents one percent of the total number of stars in the universe.

We don't know how many planets there are because we can't see them with telescopes and even if we could, they're too far away to see with current technology. We also don't know exactly how big a planet has to be before it qualifies as one (it's based on its distance from its star). So for now, let's just say "a lot" when referring to how many planets there are out there--and remember that these numbers don't count any moons or asteroids either!

In all those years we've been here on Earth, about 4 percent of the planet's surface has been covered by water.

• In all those years we've been here on Earth, about 4 percent of the planet's surface has been covered by water. The rest? Land.

• The earth is mostly covered with water -- 95% or so of it (or at least 90%). That leaves 5%, which is the land mass that makes up our planet's surface area -- approximately 510 million square miles (1 billion sq km). This is where most of us live: in North America and Europe; Australia, New Zealand and Africa; Antarctica; Oceania (the Pacific Islands); Asia; South America...and beyond!

A day on Earth lasts 24 hours and 59 minutes. This means that it takes exactly 4 minutes and 59 seconds for one complete turn of Earth on its axis, so that it crosses from one side to the other through space over and over again. This also means that an hour on our planet is actually closer to 32 minutes than it is to 60 minutes, because our clocks run slow compared to what they should be based off their longitude!

For example, if you lived in Antarctica at midnight tonight as daylight savings time ended there (it's now 1 AM), then your next sunrise will occur at 6 PM tomorrow morning instead of 7 AM as normal summertime would have dictated!

Conclusion

We hope you enjoyed learning about time, but also feel like this is just the beginning of what we can learn about it! We want to keep expanding our knowledge on this topic and make sure that everyone has the chance to understand it better
