Here's why:
* Earth's Orbit: As Earth orbits the Sun, our perspective of the night sky changes.
* Leo's Position: Leo is located in the northern celestial hemisphere, meaning it's visible from the Northern Hemisphere.
* Spring Visibility: During spring, the Earth is positioned in its orbit such that Leo is visible in the evening sky after sunset.
Finding Leo:
* Look for the "Sickle": Leo is easily recognizable by the shape of its brightest stars, which form a backward question mark or a sickle.
* Find Regulus: The brightest star in Leo, Regulus, is a blue-white giant star that marks the bottom of the sickle.
Remember, the exact timing might vary slightly depending on your specific location and the time of the night.
