Question

*Two moon on 27 August*

*27th Aug the Whole World is waiting for......... ....*

Planet Mars will be the brightest in the night sky starting August.

It will look as large as the full moon to the naked eye.

This will cultivate on Aug. 27 when Mars comes within 34.65M miles of earth. Be sure to watch the sky on Aug. 27 12:30 am.
It will look like the earth has 2 moons.

The next time Mars may come this close is in 2287.

again.

Answer 1

You have received a hoax e-mail. They circulate every summer. Loads of people must get them because Yahoo! Answers gets loads of questions on this subject.

Once upon a time a long time ago (about 60,000 BC) there was a close approach of Mars to Earth of about 34.5 million miles..

Mars did not come that close to Earth again until 27th August 2003. That was worth remarking upon as a memorable occasion and received publicity. These occasions are called perihelic oppositions.

Mars (magnitude -2.9) was marginally brighter than Jupiter (magnitude -2.8) on that date in 2003. However Venus which is both larger than Mars and nearer than Mars is (as you might expect) always brighter than Mars and varies between magnitude -3.8 and - 4.6.

So the statement in the e-mail that Mars is about to become the brightest planet in the night sky is untrue.

The hoaxers do not know much about astronomy. They just sensationalise and distort the limited facts they have managed to pick up without properly understanding them or their implications.

As Venus has never been seen as large as the Moon and Venus is always brighter than Mars, it follows that Mars will not be seen to be as large as the Moon not on 27th August nor at any other time.

The naive belief that it "could be" that large this time just reveals the hoaxers' lack of understanding of how the Sun's gravity keeps the planets in stable orbits, which means the extent to which they vary in their positions is calculable and predictable.

Humanity has been studying and predicting the planets and their orbits for 4,000 years and writing their findings up in almanacs and suddenly someone comes along and declares "an unexpected dramatic change in a stable orbit is about to occur", wlthout explaining why that should be so. And expects to be believed!?

So the hoaxers do not understand how the Sun's gravity regulates and forces planets into stable orbits and how that makes the calculating and prediction of planetary orbits possible and how humanity has done just that for 4,000 years and developed theories to explain planets' behaviour, As part of understanding some order and pattern in that behaviour and in the universe,

The hoaxers however seem to be suggesting that planets behave unpredictably and chaotically without any pattern or sense to that behaviour, and further, that they the hoaxers, like the Delphic Oracle of old, have unique divination powers and are passing on their knowledge, to which they alone are privy, to lucky old you.

Whereas all they are in fact passing on is misinformation based on their ignorance.

Mars, even at its nearest in 2003, was 140 times as far away as the Moon, and it is only twice its size (Equatorial radius of Mars = 3,402.5 km. Equatorial radius of the Moon = 1,738.14 km.).

So how could an object that is twice the size of the Moon but at least 140 times as far away (more like 220 times as far away in December 2007 when it will be 55 million miles away) ever look as big as the Moon? Does a tomato 140 yards away look as big as a cherry held at arm's length?

The only way Mars could ever appear as large as the Moon is if it were to get as close as a million miles away,

If it did do that, it would be a disaster, causing huge tidal waves on Earth and tsunamai such as we have not seen the like of before. It would not be a thing to gawp at, and say "Oh wow! Awesome!" and tell all your friends to look out for it at 12.30 am !

But of course it won't do that (come within a million miles of Earth) as Mars has a stable orbit.

The hoaxers have sent out the same e-mail every summer as regards 27 August 2004, 27 August 2005, 27 August 2006 and now 27 August 2007. Again revealing their ignorance of how the Solar System works. Mars has a year that equals 1.88 Earth years and as a result only comes close to us once every 26 months: on 27th August 2003, and then not again until 30th October 2005 and then not again until 18th December 2007.

The idea of it having a close approach on the same date every year is nonsense therefore, it is not like a wedding anniversary or a birthday or Mothers' Day, As the hoaxers seem to believe,

If anyone had have craned their necks and looked at the skies at 12.30 am on 27 August 2004 or 27th August 2006, all they would have got for their efforts was a stiff neck. As Mars was on the far side of the Sun on those two occasions and nowhere to be seen, as it was hidden behind the Sun's glare.

That is how much the hoaxers know about astronomy. That is how accurate and worthless their predictions are. Nobody should be taken in by their "knowledge" and nobody should copy and spread their e-mail to others so as "to pass on the exciting news" they have just received.

Snopes.com (see link) have a useful article on the hoax.

Answer 2

This is a hoax...the original email dates from 2003, and even then was wrong. Mars will be far from the Earth and very small this August 27, and has never ever looked as big as the Moon to the naked eye.

Answer 3

Spoof! "The email is a corrupt version of an email from August 2003 when Mars did, on an astronomical scale, make a relatively close pass to Earth. As well as leaving out the year, 2003, the email also does not mention that a telescope is needed to see Mars as big as the Moon."

Answer 4

Yes. It's a big, big exaggeration.

Mars normally brightens and dims as the two planets draw closer together, then farther apart. But although sometimes it looks very bright and impressive, it never gets anywhere near as big and bright as the Moon.

Oh, and the August 27 date was August 27, 2003. So, you missed it.

But don't be too disappointed. It wasn't THAT much brighter than it usually gets once every year or two. Still looked pretty cool, though.

Answer 5

At no time will Mars ever look as large as the full moon. It's closest approach in 60,000 years was a couple of years ago, and even then, it didn't look as large as the Moon.

Answer 6

It's crap and comes out every summer.
