The name Sunrise is of American origin and is predominantly gender-neutral. It means "Dawn," referring to the moment when the upper rim of the Sun appears on the horizon, marking the start of the Sun's path. Although the term "sunrise" is commonly used, astronomically, it occurs for only an instant when the Sun's upper limb is tangent to the horizon. The timing of sunrise varies throughout the year due to Earth's axial tilt, rotation, and orbital movement, impacting the viewer's latitude and longitude. The appearance of vibrant colors during sunrise is due to the scattering of sunlight by air molecules and particles in the Earth's atmosphere. Additionally, optical illusions and phenomena, such as the green flash and false sunrise, can sometimes be observed during this celestial event.
