Venus


Venus is the second planet from the Sun. It Venus is offen called Earth's twin because of the similarily size, and composition. It is the third-smallest planet in solar system with a diameter of about 7,519 km. The planet takes around 225 Earth days to orbit the Sun. A day on Venus is 243 Earth days long.

Venus appears as a bright star in the Earth’s sky. In fact, it is the brightest ohiect in tin:J sky flat the Sun and the Moon. It is known as ’mornng star’ and evening star as It can be seen shining brightly before sunrise and after sunset. Venus has no known moons.

Atmosphere and temperature


Venus has a dense atmosphere. It is 90 times heavier than the Earth’s atmosphere. The thick atmosphere traps most of the Sun’s heat. The surface tempereture of the planet remains around 470 °F making it the hottest planet in our solar system. The atmosphere is mostly composed of carbon dioxide. The planet is covered with several layers of clouds.
These clouds are composed of sulphuric acid. The high density and surface temperature makes it impossible for any meteor spacecraft to pass through the atmosphere. Strong Winds of more than abou 3,49.227 km/h blow in the upper atmosphere.

Density and mass


The mass of Venus is about four-fifth of Earth’s mass. An object that weighs 45 kg on Earth will weigh about 40 kg on Venus. Venus is also slightly less dense than Earth.


Surface features


Venus has a hot and dry surface. Most of the planet is covered with flat and smooth plains.The planet also has level grounds, mountains, canyons, and valleys. Atalanta Planitia, Guinevere Planitia, Lavinia Planitia are some of the broad depressions found on the planet. Around 35 per cent of the surface area of the planet comprises mountainous regions. The highest feature on the planet is Maxwell. It is around 1.6 km high and about 870.65 km long. Ishtar Terra in the northern hemisphere and Aphrodite Terra along the equator are two major highlands. Ishtar Terra is about the size of Australia and Aphrodite Terra is about the size of South America. The interior of Ishtar consists mainly of a high plateau, Lakshmi Plenum, which is surrounded by the highest mountains on Venus.

What is Microscope and who invented this amazing thing ?

Microscope A microscope is an optical instrument that is used to view objects that are invisible to the naked eye.Microscope use a combination of the images of very small objects. The first microscope were known as 'flea glasses' as they were used to view fleas or tiny creeping things.These microscope were simple tubes with a plate  and a lens at the ends.they magnified the image to more than 10 times the actual size. The first microscope the art of grinding glasses and making spectacles was known to people since the 14th century.the first microscope was made by Hans and Zacharias Jansen of the Netherlands in 1590.Hans and Zacharias Jansen were lens maker they made a microscope by placing two lenses in a tube Microscopy Microscopy is the science of examining small objects using microscope.the three branches of microscopy are optical microscopy,electron microscopy and scanning probe microscopy. Robert Hooke Robert Hooke was a British scientist. he lived i...

Solar System The solar system is a group of celestial objects located in the Milky  Way Galaxy. it is made up of eight planets. namely Mercury. Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, their moons, dwarf planets, asteroids, meteoroirls. and several other smaller celestial bodies. Astronomers believe that the solar system is around 4.5 billion years old. The solar system is about 25,000 light years from the centre of the Milky Way Galaxy. it is elliptical in shape and has the Sun at its centre. The solar system is always in motion. All the planets and celestial bodies move around the Sun in elliptical paths.  Sun   The Sun is a huge, glowing star. It is the largest and the most important object in the solar system.The Sun is composed of hydrogen, helium, and other heavier elements. It contains 99.8 per cent of the Solar system’s mass and is the main source of light and heat on Earth.  Planets   A planet is a ce...

Metals And Non-Metals | Fact & Information

-
Image
Metals and Non-metals Elements can be grouped into two broad categories-metals and non-metals. Metals are elements that are Opaque, lustrous, and good conductors of heat and electricity. lron, gold, and silver are common metals. Non-metals are elements that cannot conduct electricity or heat very well. Examples of non-metals are oxygen, hydrogen, and carbon. Only 18 elements in the periodic table are generally considered non-metals while there are over 80 metals. Properties of metals ° Metals have lustre. They are shiny when cut, scratched, or polished. ° They are malleable, that is, they can be hammered into thin sheets without breaking. ° They are good conductors of electricity and heat. ° They are ductile, that is, they can be melted and drawn into thin wires. ° All metals except mercury are solid at room temperature. ° Most metals have high melting points. Properties of non-metals ° Non-metals have no lustre, that is, they have a dull appearance. ° Th...
