Venus Drawings and Observations


Venus Nomenclature

Venus, March 19th, 2012, 23:20 - 23:40 UT, seeing fair - poor, transparency 5. TMB 130mm (5.1") f/9.25 refractor on alt-az mount. Magnification 204x. Filters used: Baader deep blue (W38A) and red (W25).

The dusky appearance was brought out by the Baader deep-blue filter. When I have observed Venus before without the deep-blue filter the dusky appearance was only noticeable near the terminator. The Baader red filter brought out the cusp extensions in the north and south polar regions. The cusps were not visible without the red filter.



Venus Compared To Earth

Like Earth, Venus is a terrestrial planet, and it is often thought of as being Earth's sister planet. It is very similar to the Earth in terms of its size and mass, and its chemical composition and density is similar.

However, the atmosphere of Venus is much more dense that Earth's, and it has clouds that are composed of sulfuric acid. Its surface temperature is about 900 degrees Fahrenheit that is hot enough to melt lead.

In addition, unlike Earth, its the rotation is retrograde, perhaps an indication that in its early history Venus was struck by a large celestial body.


Below is a collection of some of my Venus drawings and observations I have made over the years. The first time I observed Venus through a telescope and made a sketch of it was in 1976.
