2010: Mars is at its greatest distance from us these days so it appears very small

On August 27th of this year, Mars will not appear as large as the Moon again despite repeating the wrong emails from 2003. On the contrary, it is so far away that its brightness is even getting weaker

Those who participated in the observation of the Perseids on August 12 and left early saw right after sunset the planet Venus and on either side of it two small dots that are barely distinguishable - Mars and Saturn.

Mars is now on the other side of the Sun from the Earth, and therefore not only is it not approaching us, it is around the farthest point from us (and in fact, as you will see later, it will be there at the beginning of September).
This of course does not interfere with the emails that have been distributed every year since 2003 and which warn that on August 27 Mars will appear as big as the moon. Even then it wasn't like that (you needed binoculars that magnify 70 times to see details on Mars of the same size that you see with the naked eye on the moon), and there is certainly no point in waiting for that when it looks like a pale spot and actually sinks together with the sun.

According to the SEDS website The collection of astronomical data - at the beginning of August, Mars moved away from us at a distance of more than 2 astronomical units (an astronomical unit is a distance of 150 million km - the average distance between the Earth and the Sun. To illustrate, at its closest approach it is a little more than a third of an astronomical unit from us (actually Around 60 million km to be exact).

Due to its distance from us, actually on the other side of the Sun, on September 12th it crossed the brightness threshold to +1.5, and on September 4th it will become even paler and appear at +1.52 brightness. For comparison, the more distant Jupiter is on the same side of the Sun as us and its brightness is high By far - minus 2.

On September 7, it will reach the lowest descent point in its orbit and will be south of the Melaka plain for half a Mars year (Earth year).

On September 28th it will return to 1.5+ brightness and will get brighter and brighter until in a little more than a year it will approach the Earth again (again - only around 60-70 million km and even then it will not look as bright as the moon).

  1. I would be very grateful if someone could answer these questions:
    1) Does the sun itself have an orbit around the center of mass of the solar system?
    2) Does the sun itself rotate on an axis?
    3) If the sun does rotate on an axis
    3.1) What is the rotation speed. That is, how many earthly hours are one solar day (one full rotation of the sun around its axis).
    3.2) Is the axis of rotation of the sun around itself parallel to the axis of rotation of the earth around itself?

  2. A. Is there any evidence that it isn't? (I mean scientifically, of course)
    B. A star that has a cycle towards the sun - it has a cycle towards every other star in the solar system!
    (Yes. Including towards the Earth!)
    Any other statement negates any element, except the element of lying!

  3. "On September 7, it will reach the point of the most return descent in its orbit and will be south of the Melaka plain for half a Mars year (Earth year)."

    Avi,
    What is the "point of least return"?

    "Digging the chaff from the hay" has already been done and look where we've come.

    They need to be taught to "separate the wheat from the hay".

  5. In previous generations, science was taught in schools, and children could understand that what has an annual frequency is only related to the sun and not to any other body in the solar system, also anyone with logic in their head can understand that even when Mars is as close as possible to the Earth, it is not that big And you need binoculars. Since people choose to be educated in the fields of astrology and for them Mars is a planet responsible for wars or something like that, there is no way to explain, because it is easier to believe nonsense in emails.
    I return again to my criticism of the education system. The children must be taught to separate the chaff from the hay.
