Surya

Surya (/ˈsʊərjə/; Sanskrit: सूर्य sūrya, also known as Aditya, Bhanu or Ravi Vivasvana in Sanskrit, and in Avestan Vivanhant, is the chief solar deity in Hinduism and generally refers to the Sun in Nepal and India.

Surya is the chief of the Navagraha, the nine Classical planets and important elements of Hindu astrology. He is often depicted riding a chariot harnessed by seven horses which might represent the seven colors of the rainbow or the seven chakras in the body. He is also the presiding deity of Sunday. Surya is regarded as the Supreme Deity by Saura sect and Smartas worship him as one of the five primary forms of God. The Sun god, Zun, worshipped by the Afghan Zunbil dynasty, is thought to be synonymous with Surya.

Arka form

"Arka" form is worshiped mostly in North India and Eastern parts of India. The temples dedicated to the "Arka" form of Surya are Konark Temple in Orissa, Uttararka and Lolarka in Uttar Pradesh, and Balarka in Rajasthan. There was an old sun temple in Bahraich, Uttar Pradesh named Balarka Surya Mandir, built by King Tilokchand Arkawanshi in early 10th century AD which was destroyed in the 14th century during the Turkish invasions. The Surya temple in Konark was built by Ganga Vamsi king Narasimha Dev. Sun Temple, Modhera in Gujarat was built in 1026 AD by King Bhimdev of Solanki dynasty.

Alphonsus (crater)

Alphonsus is an ancient impact crater on the Moon that dates from the pre-Nectarian era. It is located on the lunar highlands on the eastern end of Mare Nubium, west of the Imbrian Highlands, and slightly overlaps the crater Ptolemaeus to the north. To the northwest is the smaller Alpetragius.

Description

The surface of Alphonsus is broken and irregular along its boundary with Ptolemaeus. The outer walls are slightly distorted and possess a somewhat hexagonal form.

A low ridge system of deposited ejecta bisects the crater floor, and includes the steep central peak designated Alphonsus Alpha (α). This pyramid-shaped formation rises to a height of 1.5 km above the interior surface. It is not volcanic in origin, but rather is made of anorthosite like the lunar highlands.

The floor is fractured by an elaborate system of rilles and contains three smaller craters surrounded by a symmetric darker halo. These dark-halo craters are cinder cone-shaped and are believed by some to be volcanic in origin, although others think they were caused by impacts that excavated darker mare material from underneath the lighter lunar regolith.
