💡Question 1: What is the hottest planet in our solar system?

Venus is the hottest planet in our solar system. You might think it's Mercury because it's closest to the Sun, but Venus has a thick atmosphere full of carbon dioxide. This creates a runaway greenhouse effect that traps heat. The surface temperature on Venus can reach a scorching 900 degrees Fahrenheit (475 degrees Celsius)! That's hot enough to melt lead. Venus is often called Earth's twin because of its similar size and composition, but don't be fooled, it's an incredibly hostile place.

Interesting Facts:
🌡️ Despite being farther from the Sun than Mercury, Venus is hotter due to its thick atmosphere.
☁️ Venus's atmosphere is mostly carbon dioxide, with clouds of sulfuric acid.
🚀 The Soviets were the first to land a probe on Venus with the Venera missions.

Difficulty Level: Medium

💡Question 2: What is the largest type of star in the universe?

The largest type of star in the universe is the blue supergiant. These stars are massive and incredibly luminous. Blue supergiants are rare and usually short-lived because they burn through their nuclear fuel quickly. One of the most famous blue supergiants is Rigel, found in the constellation Orion. These stars can be up to hundreds of times larger than our Sun and thousands of times more luminous.

Interesting Facts:
🌠 Blue supergiants are often found in young star clusters.
🪐 Despite their size, they only live for a few million years.
🌌 They end their lives in spectacular supernovae, often leaving behind neutron stars or black holes.

Difficulty Level: Hard

💡Question 3: What is the shape of the Milky Way galaxy?

The Milky Way galaxy is a barred spiral galaxy. It has a central bar-shaped structure made of stars, with spiral arms that extend outward. Our solar system is located in one of these spiral arms, called the Orion Arm. The Milky Way is vast, with a diameter of about 100,000 light-years. It's part of a group of galaxies known as the Local Group, which also includes the Andromeda Galaxy.

Interesting Facts:
🌌 The Milky Way contains over 200 billion stars.
🌠 It rotates at a speed of about 560,000 miles per hour (900,000 kilometers per hour).
🛰️ It takes our solar system about 230 million years to complete one orbit around the galactic center.

Difficulty Level: Easy

💡Question 4: Which planet has a day longer than its year?

Venus is the planet with a day longer than its year. It takes Venus about 243 Earth days to complete one rotation on its axis, but only about 225 Earth days to orbit the Sun. This means a day on Venus (one full rotation) is longer than its year (one full orbit around the Sun). Also, Venus rotates in the opposite direction of most planets in the solar system, which means the Sun rises in the west and sets in the east.

Interesting Facts:
🪐 Venus's slow rotation is still a mystery to scientists.
🌌 The planet's thick atmosphere causes extreme pressure, about 92 times that of Earth.
🌠 Venus is the second-brightest natural object in the night sky after the Moon.

Difficulty Level: Medium

💡Question 5: What is the brightest star in the night sky?

Sirius, also known as the Dog Star, is the brightest star in the night sky. Located in the constellation Canis Major, Sirius is about 8.6 light-years away from Earth. It's actually a binary star system, consisting of Sirius A, a bright main-sequence star, and Sirius B, a faint white dwarf. Sirius's brightness is due to both its intrinsic luminosity and its proximity to Earth.

Interesting Facts:
🌠 Sirius is twice as massive as our Sun and 25 times more luminous.
🪐 The name "Sirius" comes from the Greek word for "glowing" or "scorching."
🌌 It has been important in various ancient cultures, often associated with dogs due to its position in Canis Major.
