At its average distance of 42.2 million miles, light takes 3 minutes 46 seconds to reach Earth from Venus. As the planets orbit the sun that time varies between 2 minutes 13 seconds and 14 minutes 29 seconds.
The fastest way to get from place to place in our solar system is to travel at the speed of light, which is 300,000 km/sec (670 million miles per hour!). Unfortunately, only radio waves and other forms of electromagnetic radiation can travel exactly this fast.

Jan 13, 2023 · Moving at a speed of 50,000-miles per hour, it would take 32-days to reach Venus, the closest planet, and 2,250-days to reach Neptune, the furthest planet.
May 18, 2020 · A light year is the distance a photon of light travels in one year, which is about 6 trillion miles (9 trillion kilometers, or 63,000 AU). Put another way, a light year is how far you'd travel in a year if you could travel at the speed of light, which is 186,000 miles (300,000 kilometers) per second.
Mar 7, 2023 · Mercury: 77 million km (48 million miles) away from Earth on average so it takes about 3.2 minutes for light from Mercury to reach Earth. Venus: 261 million km (162 million miles) away from Earth on average so it takes about 6 minutes for light from Venus to reach Earth.
The speed of light in vacuum, commonly denoted c, is a universal physical constant that is exactly equal to 299,792,458 metres per second (approximately 300,000 kilometres per second; 186,000 miles per second; 671 million miles per hour).

On average, Venus is about 40 million kilometers (25 million miles) away from Earth. Since light travels at a constant speed, it takes approximately 186 seconds, or just over 3 minutes, for light to travel from Venus to Earth when the two planets are at their closest point.
