How far away is Mars at the speed of light?

How far away is Mars at the speed of light?

Celestial Body	Distance at Closest Approach	Light Travel Time from Earth
Moon	0.38 million km	1.25 sec
Mars	54.6 million km	3 min
Sun	150 million km	8 min
Jupiter	588 million km	33 min

Object	Time for the Light to Reach Us
The Moon	1 1/3 sec
The Sun	8 minutes
Jupiter	35 to 52 minutes
Pluto	5 1/2 hours (on average)

Unit	Definition	Distance
light-minute	60 light-seconds	1.118×107 miles
light-hour	60 light-minutes = 3600 light-seconds	6.706×108 miles
light-day	24 light-hours = 86400 light-seconds	1.609×1010 miles
light-week	7 light-days = 604800 light-seconds	1.127×1011 miles

The minimum distance from Earth to Mars is about 33.9 million miles (54.6 million kilometers). How far is that in light-seconds? Light travels at 300,000 kilometres per second, so it takes about 1.3 seconds for light to travel from the Moon back to the Earth. In other words, the Moon is 1.3 light-seconds away from the Earth.

How hot is Mars?

Temperatures on Mars average about -81 degrees F. However, temperatures range from around -220 degrees F. in the wintertime at the poles, to +70 degrees F. over the lower latitudes in the summer. Mariner 4, which flew by Mars on July 14, 1965, found that Mars has an atmospheric pressure of only 1 to 2 percent of the Earth’s. Temperatures on Mars average about -81 degrees F. However, temperatures range from around -220 degrees F. in the wintertime at the poles, to +70 degrees F. It’s relatively cool with an average annual temperature of -60 degrees Celsius, but Mars lacks an Earth-like atmospheric pressure. Upon stepping on Mars’ surface, you could probably survive for around two minutes before your organs ruptured. Many people often assume that Mars is hot, but it is farther away from the sun and has a much thinner atmosphere than Earth, so any heat it does get during the day dissipates at night. While the red planet’s thin atmosphere and bitter cold temperatures keep these frozen clouds from ever falling in the form of rain and snow we see here on Earth, there is actually a type of precipitation on Mars. This precipitation most likely takes the form of frost, NASA explains.

How many lights away is Pluto?

Pluto is located at around 263.2 light-minutes away from us. It wouldn’t take a light year to reach it. This is the average distance between Pluto and us, and even at its furthest distance from us, it wouldn’t even get near to a light-year away. The Sun is more than 8 light-minutes away. And so, if the light from the nearest star (Alpha Centauri) takes more than 4 years to reach us, we’re seeing that star 4 years in the past. It takes 499.0 seconds for light to travel from the Sun to the Earth, a distance called 1 Astronomical Unit. Distance Information Proxima Centauri, the closest star to our own, is still 40,208,000,000,000 km away.

How many people live on Mars?

There are no people on Mars, and no life that we know of. As of the year 2021, NASA has successfully landed 5 moveable rovers (like robots) on Mars for research. Currently, NASA has aspirations to have humans land on Mars in the mid to late 2030s. Long-term proposals have included sending settlers and terraforming the planet. Proposals for human missions to Mars came from e.g. NASA, Russia, Boeing, and SpaceX. As of 2022, only robotic landers and rovers have been on Mars. The farthest humans have been beyond Earth is the Moon. Long-term proposals have included sending settlers and terraforming the planet.

The farthest humans have been beyond Earth is the Moon. So you see, Mars is a very interesting place. It’s like Earth in many ways, but it’s also strange and mysterious – just like a brother. Maybe one day humans will visit or even live there, but, until then, we can continue to learn about our brother, Mars, a special part of the family of planets in our solar system.
