In theory, the closest Mars and Earth would get is when Mars reaches its closest point to the sun (perihelion) and Earth is at its farthest (aphelion). Believe of the worlds as 2 cars on a racetrack, with Earth on the within lane moving faster than Mars– completing approximately 2 laps in the exact same time it takes Mars to finish one.Mars opposition takes place when Earth “catches up” to Mars and is placed in between the sun and the Red Planet. Throughout Mars oppositions, from Earth, we can see Mars rise in the east as the sun sets in the west, with the Red Planet being noticeable in our skies all night long. Mars close technique Close technique supplies a launch chance window for missions to Mars. Range in between Mars and the sun The typical distance between Mars and the sun is 142 million miles (228 million kilometers).
The range to Mars from Earth varies substantially depending upon their orbits around the sun. In theory, the closest Mars and Earth would get is when Mars reaches its closest point to the sun (perihelion) and Earth is at its farthest (aphelion). This would bring the two planets within 33.9 million miles (54.6 million kilometers) of each other– however this has actually not yet happened in documented history according to NASA. When the 2 were 34.8 million miles (56 million km) apart, the closest taped distance to Mars from Earth was recorded in August 2003. According to NASA, the 2 will not be that close once again till the year 2237. Related: How long does it require to get to Mars? When they are both at aphelion and on opposite sides of the sun, Mars and Earth are farthest apart. Here, they can be 250 million miles (401 million km) apart according to the New York Times. The typical range between Earth and Mars is 140 million miles (225 million km). Mars orbit, opposition and seeing opportunitiesTo understand how the distance between Mars and Earth varies so much, we need to look at their orbits. Neither Earth or Mars orbit is completely circular, so the range in between the two is constantly altering. Think about the worlds as 2 vehicles on a racetrack, with Earth on the within lane moving faster than Mars– completing roughly 2 laps in the exact same time it takes Mars to finish one.Mars opposition occurs when Earth “catches up” to Mars and is positioned in between the sun and the Red Planet. During Mars oppositions, from Earth, we can see Mars increase in the east as the sun sets in the west, with the Red Planet being noticeable in our skies all night long. Such oppositions happen roughly every 26 months. Every 15 to 17 years we witness really close Mars oppositions when Earth passes in between Mars and the sun throughout Mars perihelion (closest indicate the sun). This diagram from NASA shows Earth, Mars and the sun during opposition. (Image credit: NASA) The Red Planet makes for a fascinating observing target in the night sky. It appears extremely brilliant and shows up even with the naked eye.

Mars close technique Close approach offers a launch opportunity window for missions to Mars. Here NASAs Mars 2020 mission launches from Space Launch Complex-41 on Jul. 30, 2020, bring the Perseverance rover. (Image credit: United Launch Alliance) Mars makes a close technique to Earth roughly every 26 months– the very same frequency as opposition happens, according to NASA. Due to their orbital mechanics, the closest method can occur a couple of days before or after opposition depending upon whether Mars is moving far from the Earth and sun or towards the Earth and sun respectively, according to Celestron. Not only does this time make for excellent skywatching chances but is likewise the finest time to introduce a spacecraft to the Red Planet. Lots of missions have actually taken advantage of the close distance to Mars which is why youll frequently see Mars missions launch (if spending plan enables) every 2 years. In 2020, The UAEs Hope objective launched from Japans Tanegashima Space Center on Jul. 19, Chinas Tianwen-1 mission launched from Hainan Islands Wenchang Satellite Launch Center on Jul. 23 and NASAs Mars 2020 objective launched from Floridas Space Coast on Jul. 30, bring the Perseverance rover. According to The Planetary Society, this was the very first time 3 various nations have released missions during the exact same window of chance. Distance in between Mars and the sun The average range between Mars and the sun is 142 million miles (228 million kilometers). According to a NASA reality sheet, due to Mars eccentric orbit, at its closest (perihelion) Mars has to do with 128 million miles (206 million km) from the sun and at its farthest distance (aphelion) Mars is about 154 million miles (249 million km) from the sun. The average distance in between Mars and the sun is 142 million miles (228 million kilometers). (Image credit: NASA) Measuring the range between Earth and MarsAccording to the Teachers Guide to deep space from Princeton University, the distance in between Earth and Mars was first identified by Giovanni Cassini in 1672 utilizing the parallax method.Cassini attained this by sending his fellow astronomer Jean Richer to French Guiana to perform measurements while he stayed in Paris. They took measurements of the position of Mars and triangulated those measurements with the known range between Paris and French Guiana. Cassinis estimation was just off by 7% compared to todays more precise measurements. Nowadays, with several spacecraft wandering or orbiting along the surface of the Red Planet, scientists can utilize the speed of light to identify how far away Mars is from Earth, by determining the time it takes for signals to reach Martian spacecraft, according to Universe Today.

For a great visualization of the range in between Earth and Mars and the time, it would take light to travel between the two, this animation by James ODonoghue is a good resource.
