Solar System

By Anonymous
Our Solar System consists of an average star we call the Sun,There are eight planets in the solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The four inner solar system planets (Mercury, Venus, Earth, and Mars) fall under the category of terrestrial planets; Jupiter and Saturn are gas giants(giant plants composed mostly of hydrogen and helium) while Uranus and Neptune are the ice giants (containing mainly elements heavier than hydrogen and helium).

        *Pluto, a dwarf planet, was  classified as one of the solar system planets when it was first discovered by Clyde Tombaugh. However, it is now considered to be one of the largest known members of the Kuiper Belt—a collection of icy bodies on the outer fringes of the solar system. Pluto was demoted from its planetary status in 2006 when a body of scientists decided a formalized definition for the term “planet.”

Composition Of The Solar System

The Sun contains 99.85% of all the matter in the Solar System. The planets, which condensed out of the same disk of material that formed the Sun, contain only 0.135% of the mass of the solar system. Jupiter contains more than twice the matter of all the other planets combined. Satellites of the planets, comets, asteroids, meteoroids, and the interplanetary medium constitute the remaining 0.015%. The following table is a list of the mass distribution within our Solar System.
  • Sun: 99.85%
  • Planets: 0.135%
  • Comets: 0.01% ?
  • Satellites: 0.00005%
  • Minor Planets: 0.0000002% ?
  • Meteoroids: 0.0000001% ?
  • Interplanetary Medium: 0.0000001% ?

# PSLV -C47 successfully injects #Cartosat3 spacecraft into orbit. 13 commercial satellites from USA successfully placed in their designated orbits. Polar Satellite Launch Vehicle (PSLV) is the third generation launch vehicle of India. It is the first Indian launch vehicle to be equipped with liquid stages. After its first successful launch in October 1994, PSLV emerged as the reliable and versatile workhorse launch vehicle of India with 39 consecutively successful missions by June 2017. (Cartosat-3 is an advanced Indian Earth Observation satellite built and developed by ISRO, which will replace the IRS series. Cartosat-3 will address the increased user’s demands for large scale urban planning, rural resource and infrastructure development, coastal land use and land cover etc.)                                                                                                image source:indianexpress.com

Luka Parmitano of ESA( European Space Agency)captured  our beautiful planet Earth in all its natural splendor, from 250 miles above.He is currently living and working on ISS(international space station) The European Space Agency is an intergovernmental organisation of 22 member states dedicated to the exploration of space. Established in 1975 and headquartered in Paris, ESA has a worldwide staff of about 2,200 in 2018 and an annual budget of about €5.72 billion in 2019. The  International Space Station  ( ISS ) is a  space station  (habitable  artificial satellite ) in  low Earth orbit . The  ISS programme  is a joint project between five participating space agencies:  NASA  ( United States ),  Roscosmos  ( Russia ),  JAXA  ( Japan ),  ESA ( Europe ), and  CSA  ( Canada ). The ownership and use of the space station is established by intergovernmental treaties and agreements.
