How Long Is A Terrestrial (Earth) Year?

Question

I've lived here all my life and never really knew how long, in decades, a terrestrial year lasts. Any experts on the subject?

Answer 1

The answers you have received so far have been correct, but not entirely thorough.

A terrestrial year is, in fact, the length of time it takes the Earth to travel around the sun. But what you and everyone else should be most concerned about are the extra-terrestrial years (not to be confused with "leap" years). An extra-terrestrial year is the amount of time tacked on to a terrestrial year by the space-time ripples our planet causes as it moves through space. Once this amount of time adds up to a terrestrial year, our planet slows down, while the space-time plane re-settles (like a pond after a stone is thrown into it). The last time this happened was roughly 15,000 years ago. We were stuck in one very long season, regrettably, winter. We call this long season an "Ice Age." Global warming is another such "extra-terrestrial year" in which we will be stuck in summer, while space-time once again resettles. None of this is true, of course, but it might get an interesting reaction from your teacher . . .

Answer 2

You don't have to an expert on anything to know an Earth year is 365.25 days long. Most school kids learn that early in life. Our calendars have it 365 days in a year, 366 in a leap year (every 4 years) to catch up to that extra quarter day.

A decade is 10 years, so an Earth year is .1 decades long.

What Is A Terrestrial

Answer 4

A terrestial year ( or just plainly one year) is a the amounts of time that the orbital process of the Earth takes place.
So the time on earth is a relative measurement. That means that the Earth is the basic starting point frame of reference where we take all measurement.
The Basic unit of time is the Second which relates to the time it take for an average young heart to beat one oscillation.
We have relate the number of seconds to the year.
So the Intantaneous year is based on 31.15576000 million secs in one year. I said intantaneeous as a reference point ;in reality the orbit period of the earth increases with time of few seconds per year as the Earth moves relative to the galaxies barry center.
So the value of the terrestial year continually changes but by small amount as the mass of the earth increase relative to velocity it increases its orbital radius and time together.

Answer 5

A decade is 10 years. So one year is 1/10 of a decade.

Answer 6

Depends how you measure it.

365 Days, 5 Hours, 48 Minutes, 45 Seconds. (mean Tropical Year)
OR
365 Days, 6 Hours, 9 Minutes, 9 Seconds (Sidereal year)
OR
365 Days, 6 Hours, 13 Minutes, 52 Seconds (Anomalistic year)

I personally like the first one though the second is the usual measurement I've seen for celestial bodies.

Answer 7

1/10 decade
OR
1 Earth trip around the Sun

Answer 8

A bit thick are we? What does sunlight taste like?
