Venus is the second planet from the Sun and the third brightest object in the sky of the Earth after the Sun and the Moon. Sometimes it’s called a sister planet on Earth because their size and mass are so similar.
Venus is also the closest planet on Earth. The surface of Venus is hidden by an opaque layer of clouds that are formed from sulfuric acid.
The planet is named Venus, the Roman goddess of love and beauty, and is the second-largest terrestrial planet. Read more about Venus facts.
Venus is the 2nd shining natural object in the sky. The planet has an apparent size from -3.8 to -4.6, which makes it visible on a bright, clear day. The moon is the only natural object that is brighter.
Venus is sometimes referred to as the “morning star” and “evening star”. It comes from the times of ancient civilizations that believed that Venus is two distinct stars appearing in the sky.
When the orbit of Venus is ahead of the Earth’s orbit, it changes from being visible at sunrise to be visible at sunset.
One day on Venus is longer than a year. Due to the slow rotation on the axis, one turnover takes 243 Earth days.
Venus comes from the Roman goddess of love and beauty. This may be partly due to the brightness of the planet and may come back to the Babylonians in 1581, who referred to Venus as the “bright queen of heaven.”
The Venus is sometimes called the sister planet of the Earth. This is because their size is very similar (only 638 km in diameter), and Venus has about 81% of Earth’s mass.
They are also in a similar position, and Venus is the closest planet on Earth. Both planets also have a central core, melted coat, and shell.
Venus has no moons or rings.
Other venus facts, Billions of years ago Venus’s climate was similar to Earth and scientists believe that Venus once had large amounts of water or oceans.
However, due to the high temperatures generated from extreme greenhouse effects, this water has dissolved a long time ago, and the planet’s surface is now too hot and hostile to sustain life.
Venus revolves in the opposite direction than other planets. Most other planets rotate counter-clockwise on their axis, but Venus, like Uranus, rotates clockwise.
This is called Reverse rotation that could have been caused by a collision with an asteroid or other objects that caused the planet to change its rotational path.
Another venus facts, Venus is the hottest planet in the Solar System with an average surface temperature of 462 ° C (863 ° F). In addition, Venus does not tilt on its axis, which means that there are also no seasons.
The atmosphere is a dense 96.5% carbon dioxide that retains heat and causes a greenhouse effect that evaporated all water sources billions of years ago.
The temperature on Venus is not much different during the night and day. This is due to the slow movement of solar winds on the surface of the planet.
The estimated age of the Venusian area is about 300-400 million years. For comparison, the Earth’s surface is about 100 million years old.
Atmospheric pressure Venus is 92 times stronger than on Earth.
This means that any small asteroids entering the atmosphere of Venus are crushed by enormous pressure, so there are no small surface craters on the planet. This pressure corresponds to about 1000 km below the Earth’s oceans.
Venus has a very weak magnetic field. This surprised the scientists who expected that Venus would have a magnetic field similar to Earth’s.
One possible reason is that Venus has no permanent inner core or that its core does not cool.
Venus is the only planet in the solar system whose name comes from the female form.
Venus revolves around the Sun in the ellipse, but its orbit is the closest to the circle of all planets in the Solar System.
Venus is the nearest planet on Earth. When Venus is in line with the Earth and the Sun, it is the closest planet to us, averaging 41 million kilometers (25.5 million miles) from us.
Surface of Venus
Due to the thick clouds surrounding, the details of its surface cannot be obtained by simple photographic.
Fortunately, the researchers were able to use the radar mapping method to obtain this information.
Both photography and radar imaging work, collecting the radiation that has bounced off the object, the difference lies in the accumulation of radiation.
Photography collects visible light radiation, and radar mapping collects microwave radiation.
The advantage of using radar mapping from Venus is that microwave radiation can penetrate the thick clouds of the planet, while the light necessary for the shooting is unable.
The first radar mapping of the Venusian surface with the help of a spaceship appeared in 1978 when the space probe Pioneer Venus began to orbit the planet.
Orbiting Venus Planet
The Magellan probe began orbiting around Venus. In addition to performing a radar mapping similar to the Pioneer Venus mapping, Magellan also undertook more advanced radar imaging, which collected many minor details.
The Magellan discovered were about 1,000 impact craters. Interestingly, none of the craters had a diameter of less than 2 km.
This suggests that every meteoroid small enough to create a crater with a diameter of less than 2 km would fall apart and burn down during the passage through the dense atmosphere of Venus.
An additional observation regarding the size of impact craters has helped shed light on the age of the planet’s surface. Not only the small impact craters were absent from the surface of the planet, but also those with a large diameter.
It tells us is that the surface has been formed since the heavy bombardment, from 3.8 to 4.5 billion years ago, when a large number of impact craters were created on the inner planets. Geologically, the Venusian area is relatively young.
Atmosphere Of Venus
The atmosphere of Venus can be divided into two broad layers. The first is a cloud bank that effectively surrounds the entire planet. The second is all below those clouds.
The clouds surrounding Venus extend from 50 to 80 kilometers above the surface of the planet and consist mainly of sulfur dioxide (SO2) and sulfuric acid (H2SO4).
These clouds are so dense that they reflect 60% of the sunlight that Venus receives back into space. When testing the sub-atmospheric, two characteristics are immediately visible: density and composition.
The impact of these two features on the planet is deep, which makes Venus the hottest and least hospitable of any planet in the Solar System.
It atmospheric density of around 480 ° C. This makes the surface of Venus the hottest of any planet in the solar system.
