Curiosidades incríveis sobre a famosa estrela da manhã
Sempre vai haver uma primeira estrela a aparecer, uma última estrela a se esconder do sol, e muitas vezes estas estrelas são consideradas como responsáveis por diversos simbolismos. A famosa estrela da manhã está entre as mais conhecidas estrelas, mas por acaso você sabia que ela na verdade nem é uma estrela, mas sim um planeta?

Venus is actually the famous morning star, and is also the second planet in order of distance from the sun in our solar system, making its full orbit every 224.7 days.
This planet was named after the famous Greco Roman goddess, Venus, also known as Aphrodite. After the moon itself, the morning star is the most intensely bright celestial object in the night sky, having an apparent magnitude of -4.6, sufficient to produce shadows.
Details about the Morning Star and its relationship with Earth
Since Venus is much closer to the sun than Earth, it can generally be seen in the same direction as the sun. It reaches its maximum brightness around a few hours before sunrise, or dawn, as some call it, which is why the planet is generally known as the morning star, or evening star, sometimes also called the shepherd’s star.
Venus is widely known as a terrestrial-type planet, also called telluric, and is considered Earth’s sister, as both celestial bodies are extremely similar in their sizes, as well as in their mass and composition.
However, Venus is covered by a broad opaque layer of sulfuric acid clouds, which is extremely reflective, which prevents its surface from being visible from ordinary visible outer space. Its atmosphere is really dense, being the densest among all the terrestrial planets in our solar system, being mainly made up of carbon dioxide.
However, the morning star does not have a carbon cycle to fix it in its rocks or any other type of component on its surface, and it does not even show any sign of organic life that can absorb carbon as biomass.
Scientists believe that in the past Venus had several oceans, just like Earth, but these ended up evaporating when the temperature rose, leaving behind an extremely desert-like, dusty and dry landscape, with several plate-shaped rocks.
It is assumed that the water probably ended up dissociating due to the total lack of an electromagnetic field, which meant that the hydrogen ended up being dragged into space by the solar winds.
For a long time the Venusian surface was the subject of much speculation, until some secrets were finally revealed by the incredible planetary science of the 20th century. It was in this century that the planet’s surface was finally mapped in detail by the incredible Magellan program.
The soil of the morning star presents several evidence of intense and extensive volcanism, while the sulfur in the atmosphere may end up indicating that some eruptions were actually quite recent.
However, due to the lack of evidence of an existing magma flow accompanying the most visible calderas, it remains a huge enigma. Venus is a planet that does not have many impact craters, which actually shows that its surface is relatively young, with an approximate age of more than 600 million years.
There is no evidence of the existence of plate tectonics, which is possibly because the planet’s crust is too strong to be reduced, as there is no water to make it less viscous.
The morning star myths
As one of the brightest objects in the entire sky, the morning star has been well known since ancient, even historical, times and, as such, has gained an important position within human culture itself.
It was even described in Babylonian cuneiform texts, such as the famous plaque of Venus se ammisaduqa, in which several observations are reported that very possibly date back to more than 1600 years before Christ. The ancient Babylonians called the morning star Ishtar, the goddess and personification of femininity itself, as well as the goddess of love.
The Egyptians believed that Venus was actually two distinct bodies and thus knew the morning star as Tioumoutiri, and the evening star as Ouaiti. On the other hand, the Greeks called the morning star phosphorus, or Eoaphorus. Later they changed the name to Aphrodite.
Meanwhile, the Romans named the star Venus, but a Roman naturalist named Pliny ended up calling the morning star Isis in his studies. In Persian mythology, the planet was usually associated with the goddess Anahita. There were several religions that associated the morning star with some divinity, especially those related to love and fertility.
For the Mayans, this planet was essential, as their religious calendar was partially based on the movements carried out by the star, taking them into account to determine favorable times for various events, such as wars and sacrifices.
