ES FALSO QUE EN AGOSTO 2011,MARTE Y LA LUNA SE VERÁN DEL MISMO TAMAÑO.

(THAT IS WRONG THAT IN AUGUST 2011, MARS AND THE MOON WILL BE SEEN OF THE SAME SIZE.)

A pps which says that, in August 2011, Mars and the Moon will have the same size, seen from the earth.

At the end, there is a translation to English (Very important, since 2009, each year by June, starts to circulate this pps, wich is completeley false.)

Si ustedes reciben esta pps, no la crean. Marte jamás se verá del tamaño de la Luna.

Apoastro: Máxima distancia

Periastro: Mínima distancia.

La Tierra y Marte tienen órbitas elípticas.

La Tierra:

Periastro = 147Millones de Km

Apoastro = 152 Millones de Km

Marte

Periastro = 206 Millones de Km

Apoastro = 249 Millones de Km

La mayor cercanía de La Tierra y Marte es cuando La Tierra esté en su Apoastro y Marte en su Periastro y estén alineadas con el Sol.

Menor distancia Tierra - Marte = 206 - 152 = 54 Millones de Km

Diámetro de Marte = 6794 Km

Diámetro angular de Marte (Observado desde la Tierra en su momento de mayor cercanía) = 6794/54'000,000km= 0.00012581 radianes

= 25 Segundos.

La Luna

Diámetro angular máximo: 33 minutos 28 segundos

Diámetro angular mínimo: 29 minutos 23 segundos.

Compare 29 minutos 23 segundos con 25 segundos.

Comparemos: (29x60+23)/25 =71

O sea que Marte, en este caso particular de máximo acercamiento, se verá sólo 1/70 del tamaño de la Luna.

Por favor no se trasnochen en Agosto y a cada persona que les envíe esta pps devuélvale este comentario.

(English)

If you receive this pps, please don't believe what it says. Mars never will be seen of the size of the moon.

Apoastron: Maximum distance

Periastron: Minimum distance.

Earth and Mars have elliptical orbits.

Earth

Periastron = 147Millons Km

Apoastron = 152 Million Km

Mars

Periastron = 206 Million Km

Apoastron = 249 Million Km

The closer proximity between Earth and Mars is when Earth is in Apoastron and Mars in its periastron and both are aligned with the Sun

Minor distance Earth-Mars = 206 -152 = 54 Million Km

Diameter of Mars = 6794 Km

Angular Diameter of Mars (Observed from Earth at its peak close) = 6794Km/54'000,000Km = 0.00012581 radians

= 25 Seconds.

Moon

Maximum angular diameter: 33 minutes, 28 seconds

Least Angular diameter: 29 minutes, 23 seconds.

Compare 29 minutes 23 seconds to 25 seconds.

Let's compare: (29x60 +23) / 25 = 71

So, in this case, when Mars is in the closest approach to Earth this relation will be only 1 / 71 of the size of the Moon.

Please do not stay up in the nights of August of 2011 and send this comment, to every person that send to you this pps.

Since 2009, each year beginning June, begins to move this pps through the web, which is completely false.
