Venus is the brightest planet in our Solar System, and it can be seen with the unaided eye from Earth. Venus is so bright that it has been given the nickname of the “evening star” and “morning star” due to its consistent presence in the night sky. It is the second planet from the Sun and has an albedo of 0.7, meaning that it reflects around 70% of the sunlight that reaches it.
The brightness of Venus is due to its thick atmosphere which is composed of 96.5% carbon dioxide and 3.5% nitrogen. This atmosphere is much thicker than Earth’s, and it is what causes Venus to be so bright. The thick atmosphere also traps the heat from the Sun, making Venus the hottest planet in the Solar System with an average surface temperature of 864°F (462°C).
Venus is the brightest planet in the Solar System, but it is not the closest planet to the Sun. That title belongs to Mercury, which is only 58 million kilometers away from the Sun. However, Mercury is much darker than Venus, reflecting only around 10% of the sunlight that reaches it. This is due to its lack of atmosphere, which means that it is unable to trap the heat from the Sun like Venus does.
Venus is also much brighter than the other planets in the Solar System. Mars, for example, is much further away from the Sun than Venus and reflects only around 25% of the sunlight that reaches it. Jupiter is even further away and reflects only around 35% of the sunlight that reaches it.
The brightness of Venus can also vary depending on its position in relation to the Sun. When Venus is between the Earth and the Sun, it is at its brightest. This is known as its “greatest illuminated extent” and it occurs when Venus is at its closest point to the Earth. When Venus is on the opposite side of the Sun from the Earth, it is at its dimmest.
