Do you know the speed of light to Mars? To know it, keep reading this article. Do you know? The speed of light is constant nev it traveled through different mediums. For example, the speed of light in a vacuum is equal to the speed of light in air or on a curved rod. While talking about Mars, is the 4th planet from the Sun. It is cold, dusty, and a desert world with very thin atmospheric conditions. Light speed is so fast that any material object can travel through space. This is, of course, barring the existence of theoretical shortcuts in the fabric of space called wormholes. Let’s take a look at the speed of light to Mars.

**What Is The Speed Of Light To Mars? **

The speed of light to mars is approximately 186,282 miles per hour which is equivalent to 299,792 km per second. How long does it take to get to mars from earth at the speed of light? Well, if you traveled at the speed of light, it would take 3 to 2 minutes to reach Mars. because the distance from Earth to mars is 153.79 million km. Similarly, the distance from earth to mars in light years is also 153.79 million km. Now, after hearing this much distance you may be curious to know, when will humans go to Mars. Well, NASA is under presidential orders to land humans on Mars by 2023 and later on in 2023.

Due to this speed, the light shining from the surface of Mars would take different times such as given below,

- The farthest approach – is 1342 seconds or 22.4 minutes
- Closest approach – 187 second or 3.11 minutes
- Closet possible approach – 182 seconds or 3.03 minutes
- The average time is – 751 seconds or just over 12.5 minutes

Now, you know how long does it take to get to mars at the speed of light as well as the speed of light from earth to mars.

**Calculate The Speed Of Light To Mars **

The speed of light to Mars is calculated by using the formula,

Vkm/h = (D)km/(T)hr

Here, V is the speed of light to Mars

D is the total distance

T is the time

The km/h is a unit of speed in the metric SI system. Kilometers per hour can be abbreviated to km/h, and sometimes to km/h. So, the speed in km/h is equal to the distance in kilometers divided by the time.

So you can find the speed of light in km/h in exponential notation. You can also use other formulas like,

**c = λf **

Here, λ is the wavelength in meter

f is the frequency in Hz

**For Example **

The light reaches Mars at a speed of 299,792 km per second. Then find how long to mars at speed of light?

Well, you know the distance of Mars from the Earth is around 153.79 million km.

By using a basic speed-distance formula. The time required to reach mars is,

Time = 153.79/299,792

= 2.5 minutes

Now, you got how long to get to mars at speed of light.

**About Mars **

Mars is a fourth planet from the Sun and has a different rusty red appearance, therefore, it is called Red Planet also, and has two unusual moons. The red planet is a cold, desert world, with a very thin atmosphere. But the dusty, lifeless planet is far from dull. The bright red color of the planet is known due to iron-rich minerals in its regolith, and the loose dust and rock covering its surface.

Mars has the largest Volcanoes in the solar system, Olympus Mons is one of them. The immense volcano, which is about 370 miles in diameter, is broad enough to cover the state of New Mexico.

**FAQ**

**How Long Does It Take The Speed Of Light To Reach Mars?**

As that 60-second clip of O’Donoghue’s full movie on YouTube shows, light takes 3 minutes 2 seconds to travel between Earth and Mars at closest approach. That’s six minutes and four seconds for a light-speed round-trip.

**How Many Light Minutes Away Is Mars?**

At its average distance of 142 million miles, light takes 12 minutes and 42 seconds to reach Earth from Mars. As the planets orbit the Sun, this time varies between 3 minutes 13 seconds and 22 minutes 16 seconds.

**How Long Will It Take To Get To Mars With The Speed Of?**

Cruise. The cruise phase begins after the spacecraft separates from the rocket, soon after launch. The spacecraft departs Earth at a speed of about 24,600 mph (about 39,600 kph). The trip to Mars will take about seven months and about 300 million miles (480 million kilometers).

**How Bright Is Day On Mars?**

Mars’ greater distance from the Sun means that the maximum intensity (brightness) of sunlight on Mars is much less (about 44%) than that on Earth.

**How Long Would It Take To Travel 6 Trillion Miles?**

A light-year is the distance a beam of light travels in **a single Earth year**, which equates to approximately 6 trillion miles (9.7 trillion kilometers). On the scale of the universe, measuring distances in miles or kilometers is cumbersome given the exceedingly large numbers being discussed.

**Conclusion **

Above, we have provided all the basic information and formulas for a detailed calculation of the speed of light. Many scientists and physicists have tried to calculate the speed of light throughout history. For example, Galileo tried to measure the speed of light in the 17th century. A more accurate measurement of the speed of light was made in Europe in 1849 by Hippolyte Fizeau. This was all about the speed of light to Mars.
