Today, Mars is believed to be largely tectonically inactive. However, observational evidence and its interpretation suggests that this was not the case further back in Mars's geological history. At the scale of the whole planet, two large scale physiographic features are apparent on the surface. The first is that the northern hemisphere of the ...
In 2016, the International Astronomical Union (IAU) organized a Working Group on Star Names (WGSN) [2] to catalog and standardize proper names for stars. The WGSN's first bulletin, dated July 2016, [3] included a table of 125 stars comprising the first two batches of names approved by the WGSN (on 30 June and 20 July 2016) together with names of stars adopted by the IAU Executive Committee ...
The geological history of Mars can be broadly classified into many epochs, but the following are the three major ones: Noachian epoch (named after Noachis Terra): Formation of the oldest extant surfaces of Mars, 3.8 billion years ago to 3.5 billion years ago. Noachian age surfaces are scarred by many large impact craters.
This is a list of craters on Mars. Impact craters on Mars larger than 1 km (0.62 mi) exist by the hundreds of thousands, but only about one thousand of them have names. [ 1 ] Names are assigned by the International Astronomical Union after petitioning by relevant scientists, and in general, only craters that have a significant research interest ...
The orientation of Mars's axis is such that its north celestial pole is in Cygnus at R.A. 21 h 10 m 42 s Decl. +52° 53.0′ (or more precisely, 317.67669 +52.88378), near the 6th-magnitude star BD +52 2880 (also known as HR 8106, HD 201834, or SAO 33185), which in turn is at R.A. 21 h 10 m 15.6 s Decl. +53° 33′ 48″.
Mars retrograde is as confused as it is confusing. It’s unmooring and can bring waves of utterly unexpected events. You probably don’t need a recap, but let’s take a look at some of what’s ...
Today, names of Martian features derive from a number of sources, but the names of the large features are derived primarily from the maps of Mars made in 1886 by the Italian astronomer Giovanni Schiaparelli. Schiaparelli named the larger features of Mars primarily using names from Greek mythology and to a lesser extent the Bible.
The Memnonia quadrangle is also referred to as MC-16 (Mars Chart-16). [1] The quadrangle is a region of Mars that covers latitude -30° to 0° and longitude 135° to 180°. [2] The western part of Memnonia is a highly cratered highland region that exhibits a large range of crater degradation. Memnonia includes these topographical regions of Mars:
