  Facts About VENUS

DiD U Know!   Planet VENUS. The second planet from the Sun is Venus. It is frequently referred to as Earth's "twin" or "sister" planet since it is almost as big and comparable in makeup. Like Mercury, Venus is an inner planet to Earth and is always close to the Sun whether it appears in the night or morning sky. Venus is the brightest natural object in Earth's sky other than the Sun and Moon. It may create visible shadows on Earth in low light and can be seen with the unaided eye in brilliant sunlight. In this article I will tell you about amazing facts about planet VENUS. So let’s start:

Size:

• The planet measures 7,521 miles (12,104 kilometers) wide, compared to Earth's 7,926 miles (12,756 kilometers), making it almost as large all around as Earth.
• After the Moon, Venus is the brightest object visible from Earth in the night sky.

Atmosphere:

• Of the terrestrial planets, which also include Mercury, Earth, and Mars, Venus has the densest atmosphere.
• More than 96 percent of it is carbon dioxide, and only 3.5 percent of it is atomic nitrogen.
•  Other gases such as carbon monoxide, sulphur dioxide, water vapour, argon, and helium are present in trace levels.
•  The atmospheric pressure at the planet's surface varies with surface elevation; it is about 95 bars, or 95 times the atmospheric pressure at the surface of Earth, at the elevation of the planet's mean radius.
• The Earth's seas contain this similar pressure at a depth of around 1 km (0.6 miles).
• The upper atmosphere of Venus covers the planet from the furthest reaches of space to a height of roughly 100 km (60 miles).
•  There, the temperature changes greatly throughout the day and night, peaking at around 300-310 kelvins (K; 80-98 °F, 27-37 °C) during the day and 100-130 K (280 to 226 °F, 173 to 143 °C) at night.
• There is an extremely cold layer with a temperature of around 100 K located at a height of about 125 km (78 miles).
• From around 173 K (148 °F, 100 °C) at 100 km above the surface to approximately 263 K (14 °F, 10 °C) at the top of the continuous cloud deck, which is located at a height of more than 60 km, the temperature in the middle atmosphere rises steadily with decreasing altitude (37 miles).
• The temperature rises rapidly in the lower atmosphere, or troposphere, below the cloud tops until it reaches 737 K (867 °F, 464 °C) at the surface at the planet's mean radius.
• This temperature exceeds the point at which lead or zinc will melt.
• Venus's huge atmosphere has a significant impact on the planet's surface temperature because it creates a tremendous greenhouse effect.
• Venus actually absorbs less sunlight than Earth because of its brilliant, constant cloud cover.
• However, the sunlight that does break through the clouds is absorbed both at the surface and in the lower atmosphere.
• This energy is reradiated at infrared wavelengths by the surface and the gases of the lower atmosphere, which are warmed by the absorbed light.
• The majority of reradiated infrared radiation on Earth escapes back into space, allowing Earth to keep its surface temperature relatively cold.
• On Venus, in contrast, a large portion of the infrared radiation is trapped by the planet's thick cloud layers and dense atmosphere of carbon dioxide.

Composition:

• Numerous Soviet landers were equipped with tools for examining the chemical make-up of Venus' surface components.
•  There is no conclusive knowledge of the sorts of rocks or minerals present since only the relative amounts of a few elements were measured.
•  The abundances of several elements were measured using two methods. The Soviet Vega 1 and 2 missions' landers and Veneras 8, 9, and 10 all carried gamma-ray spectrometers that were used to detect the quantities of naturally radioactive isotopes of the elements uranium, potassium, and thorium.
• On Veneras 13 and 14, as well as Vega 2, X-ray fluorescence equipment were used to measure the amounts of many important elements.
• The highest heights of Venus have anomalously high radar reflectivity, which is an unexpected finding from orbital radar measurements.
• The most likely explanation is that there is a thin coating of some semiconducting substance covering the highest peaks.
•  Although its composition is unclear, it could be an iron-containing mineral like pyrite or magnetite, which originated at colder, higher elevations from low air quantities of iron(II) chloride vapour.

Unbelievable Facts:

1. The nearest planet to Earth in the solar system is Venus. She is the second planet and is occasionally referred to as our "sister planet" due to the fact that her diameter and density are so similar to our own.
2. Venus is the brightest object in the sky, followed by the Sun and the Moon. The planet is sometimes referred to as the "morning star" because it appears in the morning or evening sky like a brilliant star.
3. Sunlight reflecting off the glossy sulfuric acid clouds gives Venus a creamy-white radiance that is strangely constant. Rarely does she smile.
4. But when viewed from a dark location, Venus is brilliant enough to cast shadows. Wait until the new Moon phase, when there won't be any competition from the Moon.
5. As far as we know, the surface of Venus is dotted with craters, volcanoes, mountains, and enormous lava plains.
6. Venus is the planet in the known cosmos that is the most miserable, despite its lovely name! Its surface is always 850 degrees, making it hotter than a wood stove.
7. The air is 100 percent carbon dioxide, catching in the sun's intensity like a cover. Venus figures out how to have a more blazing surface than even Mercury. This was the first 'nursery impact' model some time before that expression's ongoing notoriety.
8. Venus' environment so thick it would smash you. The planet's gaseous tension remaining parts stuck at 90 Earth-pressures, making it the most effective strain cooker in this neck of the system. A couple of moments would do it for meat stew.
