A minor planet is a term used to describe an astronomical object that is neither a dominant planet nor a comet and thus includes the dwarf planets that orbit around the Sun.

Minor planet 4538 Vishyanand was discovered on 10 October 1988 by Japanese astronomer Kenzo Suzuki which is located somewhere between Mars and Jupiter.

Answer: (b)

A Solar Thermal Power Plant of 140MW at Mathania in Rajasthan has been proposed and sanctioned by the Government in Rajasthan.

The project configuration of 140MW Integrated Solar Combined Cycle Power Plant involves a 35MW solar power generating system and a 105MW conventional power component and the GEF has approved a grant of US$ 40 million for the project. The Government of Germany has agreed to provide a soft loan of DM 116.8 million and a commercial loan of DM 133.2 million for the project.

Marwar Mathania is a town in Jodhpur district, Rajasthan, India. It is well connected by roads and railways to Jodhpur city. The Yazd integrated solar combined cycle power station is a hybrid power station situated near Yazd, Iran which became operational in 2009. It is the world’s first combined-cycle power plant using solar power and natural gas.

Note: The International Solar Alliance (ISA) is an alliance of more than 120 countries, which come either completely or partly between the Tropic of Cancer and the Tropic of Capricorn.

This initiative was first proposed by Indian Prime Minister Narendra Modi. The alliance’s primary objective is to work for efficient exploitation of solar energy to reduce dependence on fossil fuels.

In January 2016, Narendra Modi, and the French President François Hollande jointly laid the foundation stone of the ISA Headquarters and inaugurated the interim Secretariat of the ISA at the National Institute of Solar Energy (NISE) in Gwalpahari, Gurugram.

Ocean Thermal Energy Conversion (OTEC) uses the temperature difference between cooler deep and warmer shallow or surface ocean waters to run a heat engine and produce useful work, usually in the form of electricity.

However, the temperature differential is small and this impacts the economic feasibility of ocean thermal energy for electricity generation. The most commonly used heat cycle for OTEC is the Rankine cycle using a low-pressure turbine.
