Facts about Mars

Venus

 Venus is the second planet from the Sun in the Solar System. It has the name of the Roman goddess of beauty and love. With an apparent magnitude of 4.6, it is the second-brightest natural object in the night sky after the Moon and is occasionally visible to the unaided eye in the middle of the day.

Due to their similar size, mass, proximity to the Sun, and overall composition, Venus and Earth are both categorized as terrestrial planets and are occasionally referred to as "sister planets." In other ways, it differs greatly from Earth. With an atmosphere made up of more than 96% carbon dioxide, it has the densest atmosphere of the four terrestrial planets.

The planet's surface has an atmosphere with 92 times the pressure of Earth. Despite Mercury being closer to the Sun, Venus is by far the warmest planet in the Solar System, with a mean surface temperature of 735 K (462 °C; 863 °F). Venus' surface cannot be seen in visible light from space due to an opaque layer of sulfuric acid clouds that are highly reflective.

Top ten facts about Venus.

1. Venus is the brightest object in the night sky.

• After the Moon and Jupiter, it is the third-brightest natural object in the night sky. Venus is frequently visible in the east just before dawn and in the west just after dusk. The "Morning Star" and the "Evening Star" are the names given to it.

2. Clouds of sulfuric acid are present in Venus' atmosphere.

• Yes, there are sulfuric acid clouds in Venus' atmosphere. Venus has an extremely thick atmosphere that is primarily formed of sulfuric acid clouds and carbon dioxide. The planet's extraordinary temperatures are brought on by the thick layer of sulfuric acid clouds that form, reflecting sunlight and trapping heat in the atmosphere.

3. Venus's surface is extremely hot and dry.

• Venus' surface is blanketed in an atmosphere that is 95.5% carbon dioxide and 4.5% nitrogen and is rich in sulfuric acid. Venus's surface is extremely dry and devoid of liquid water. The terrain is covered in basalt and other igneous materials, and the surface is dotted with hundreds of volcanoes and mountains. The average temperature of Venus is up to 870°F (467°C).

4. Only Venus rotates in the direction of the sun (retrograde rotation).

• Venus is the only planet in our Solar system which rotates in the direction of the Sun i.e. clockwise (retrograde rotation), all of the other planets rotate in the opposite direction from the Sun i.e. anti-clockwise (pro-grade rotation).

5. Venus doesn't have any moons or rings.

• No, Venus does not have any moons or rings. In addition, the extreme heat of Venus' surface and the intense gravitational pull of the planet cause any large objects that come near to be pulled in and destroyed.

6. Venus is 67.24 million miles far from the Sun.

• The exact distance of Venus from the Sun can vary due to its elliptical orbit. At its closest, Venus is roughly 41 million miles (66 million km) from the Sun. At its farthest, Venus is roughly 93 million miles (150 million km) from the Sun.

7. Venusian days are 243 days longer than Earth.

• Venus rotates around its axis far more slowly than Earth does, which explains why, Venusian days are equal to 243 Earth days. Venus rotates slowly, taking 243 Earth days to complete one circle around its axis, which accounts for the significant difference in day lengths.

8. Venus's pressure would crush you.

• Around 92 times as much pressure exists in Venus' atmosphere as there is on Earth. This implies that you would be crushed by the intense pressure if you were to go onto Venus' surface without any safety gear. This is because the atmosphere is significantly thicker than that of Earth because of the enormous amounts of carbon dioxide present.

9. Venus doesn’t have liquid water.

• Venus's tremendous warmth prevents liquid water from existing on its surface. Around 860°F is the surface temperature of Venus, which is hot enough to melt lead. Water cannot exist in liquid form on the surface since there isn't an atmosphere that can capture and hold heat from the Sun. In addition, the atmosphere of Venus is primarily composed of carbon dioxide, which prevents the presence of water vapor in the atmosphere.

10. Venus bears the name of a Roman goddess.

• The Roman goddess of love and beauty is named Venus. She is also referred to as the goddess of gardens, spring, and fertility. According to myth, Venus is the mother of Cupid, the romantic god.

 BONUS

The ancient Egyptians believed Venus to be two distinct objects—a morning star and a separate evening star. But because Venus could be seen in the night sky, people were aware of it long before that.

Galileo Galilee, an astronomer, was the first to observe Venus using a telescope. In 1610, he made the planet's first precise observations.
