Venus

-
Hii , welcome to my post . Today we are going to know about Venus (planet). So let's start :

Definition: 
• Venus is the second planet from the Sun.
• It is sometimes called Earth's "sister" or "twin" planet.
• It is almost as large and has a similar composition
  like  Earth. 
• As an interior planet to Earth, Venus (like Mercury) 
  appears in Earth's sky, either as morning Star or
  evening star.
• Aside from the Sun and Moon, Venus is the brightest
  natural object in Earth's sky.
• It is capable of casting visible shadows on Earth at
  dark conditions.
• It is being visible to the naked eye in broad daylight.
• Venus is one of the four inner terresterial planets. 
Facts :
• Venus was the first planet explored by a spacecraft.
• It was intensely studied early in the history of space
  exploration.
• Venus was also the first planet whose surface was
   reached by a spacecraft from Earth.
• The intense heat means landers have only survived
   for a couple of hours.
• Venus rotates backward on its axis compared to most
   planets in our solar system.
• This means the Sun rises in the west and sets in the
   east, opposite of what we see on Earth.
• Venus is an unlikely place for life as we know it, but
  some scientists theorize microbes might exist high in
  the clouds where it’s cooler and the pressure is
  similar to Earth’s surface. Phosphine, a possible
  indicator of microbial life, has been observed in the
  clouds.
• Venus rotates very slowly on its axis – one day on
  Venus lasts 243 Earth days. 
• The planet orbits the Sun faster than Earth, however,
   so one year on Venus takes only about 225 Earth
   days, making a Venusian day longer than it.

Quick Facts : 
Mass (1024kg)-------                       4.87
Diameter (km)------                          12
Density (kg/m3)-------                      5243
Gravity (m/s2)------                           8.9
Escape Velocity (km/s)----              10.4
Rotation Period (hours)------           5832.5
Length of Day (hours)------              2802
Aphelion (106 km)-----                     108.9
Orbital Period (days)-------               224.7
Orbital Velocity (km/s)------             35
Orbital Inclination (degrees)-------   3.4
Orbital Eccentricity-------                  0.007
Obliquity to Orbit (degrees)------     177.4
Mean Temperature (C)-----              464
Surface Pressure (bars)--------        92

Composition: 
• Venus has a thick, toxic atmosphere filled with carbon
  dioxide.
• Venus has an extremely dense atmosphere
  composed of 96.5% carbon dioxide, 3.5% nitrogen—
  both exist as supercritical fluids at the planet's
  surface.
• It’s perpetually shrouded in thick, yellowish clouds of
   sulfuric acid that trap heat, causing a runaway
   greenhouse effect.
 • It’s the hottest planet in our solar system, even
   though Mercury is closer to the Sun.
• Surface temperatures on Venus are about 900
  degrees Fahrenheit (475 degrees Celsius) – hot
  enough to melt lead. 
• The surface is a rusty color and it’s peppered with
   intensely crunched mountains and thousands of
   large volcanoes. 
• Venus has a solid surface covered in dome-like
  volcanoes, rifts, and mountains, with expansive
  volcanic plains and vast, ridged plateaus.

Structure: 
• Venus is not a gas planet, but a rocky planet. 
• Mainly structure of Venus consists of Crust, Mantle,
  and Core.
 (i) Crust :
     • Venus' crust is mostly basalt and is estimated to
        be 6  to 12 miles (10 to 20 km) thick. 
 (ii) Mantle :
     • Venus' molten rocky mantle is roughly 1,200 miles
       (3,000 km) thick.   
 (iii) Core :
     • The interior of Venus is made of a metallic iron
       core that's roughly 2,400 miles (6,000 km) wide.

 Hii, welcome to  my post. Today we are going to know about Space ,  So let's start :   • Space is the boundless three dimensional extent in which objects and events have relative postion and direction.  • Space is continuous area or expansion which is free , available and unoccupied.  • It is a vacuum devoided of matter where sound cannot travel.  • It is the zone above and around our planets where there is no air to breathe  or light to scatter. • Space is one of the few fundamental quantities in physics,  meaning that it cannot be defined via other quantities because nothing more fundamental  it known at present. On the other hand , it can be related to other fundamental quantities.  • Our solar system is part of space. Like our solar  system, billions of other solar system  are present  in Space. • Billions of stars , galaxies, planet etc are part of space. • Billions of commets , asteroid,  bla...

 Hii , welcome to my post. Today we are going to know about solar system. So let's start. • The Solar System is the gravitationally bound system of the Sun and the objects that orbit it. • It formed 4.6 billion years ago from the   gravitational collapse of a giant interstellar           molecular cloud.  •Formation of solar system is described by bing bang theory . • Solar system consist of 8 planets . Before 2006 there were 9 planets in the solar system, but in 2006 the ninth planet "Pluto" was removed from our solar system.   • The order of the planets in the solar system,               starting nearest the sun and working outward is       the following: Mercury , Venus , Earth Mars ,                  Jupiter , Saturn , Uranus , Neptune and then the           possible Planet Nine Plu...

At the beginning of your trip through space, you might recognize some of the sights. The Earth is part of a group of planets that all orbit the Sun – with some orbiting asteroids and comets mixed in, too. A diagram of the solar system, showing the sun and its orbiting planets. A familiar neighborhood. Mark Garlick/Science Photo Library via Getty Images You might know that the Sun is actually just an average star, and looks bigger and brighter than the other stars only because it is closer. To get to the next n hii earest star, you would have to travel through trillions of miles of space. If you could ride on the fastest space probe NASA has ever made, it would still take you thousands of years to get there. If stars are like houses, then galaxies are like cities full of houses. Scientists estimate there are 100 billion stars in Earth’s galaxy. If you could zoom out, way beyond Earth’s galaxy, those 100 billion stars would blend together – the way lights of city buildin...

Hii , welcome to my post . Today we are going to know about Mercruy (planet). So let's start : Definition : • Mercury is the smallest planet in the  Solar system   and the closest to the Sun . • Its orbit around the Sun takes 87.97 Earth days, the   shortest of all the Sun's planets. • It is named after the Roman god Mercurius (Mercury),   god of commerce, messenger of the gods, and   mediator between gods and mortals, corresponding   to the Greek god Hermes. • Like Venus , Mercury orbits the Sun within Earth 's     orbit as an inferior planet. • Its apparent distance from the Sun as viewed from   Earth never exceeds 28°.  • This proximity to the Sun means the planet can only    be seen near the western horizon after sunset. Facts :  • Mercury rotates in solar system in unique way.  • Mercury is the planet that orbits the closest to the    Sun.  • Mercury is the smallest pla...

Hii, welcome to my post . Today we are going to know about sun. So let's get started.   Definition: • The Sun is a star at the center of the Solar System,     about which planets of the solar system revolve. • It is a nearly perfect ball of hot plasma. • The Sun's radius is about 695,000 kilometers . • Sun is 109 times bigger than the Earth. • Its mass is about 330000 times that of Earth. • The Sun comprises  about 99.86% of the total mass. Facts: • The sun is a yellow dwarf star in the center of the   solar system. • It is the largest, brightest and most massive object in   the system. • The sun formed around 4.5 billion years ago. • The heat and light from this nuclear reaction enabled    life on Earth to evolve and prosper. Quick facts :   (i) Equatorial diameter ----- 1.39 M KM. (ii) Mass ---- 1.99 x 10 ³⁰ KG . (iii) Gal. Centre distance ---- 26038 light year . (iv) Roatationa...
