Certainly not within the Sun’s lifetime. The rate of deceleration is decreasing. What happens is that the tidal wave that the Moon pulls around the Earth is actually at an angle from the line that connects the gravitational centres of Earth and Moon, and is big enough to tug at the Moon. So the Moon gains momentum at the expense of Earth’s torque and inches to an ever higher orbit. (See an illuminating explanation of how the tides really work.)

In about two billion years (if memory serves) the Moon will be too far away to cause a totality when transiting in front of the Sun during solar eclipses. We live today in the era of the Earth-Moon system where the Moon is just far enough away to cover the Sun’s disc exactly in a total eclipse that leaves the corona visible.

Makeshifts last the longest.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
