NASA released an interesting image that looks like a potato, but it is not. This photo was taken by the most powerful camera ever sent to another planet. It is Phobos, the largest of the two jagged moons of Mars. The other satellite of this red planet is called Deimos. In an Instagram post, the space agency stated that this photo was taken by the HiRISE camera on the Mars Reconnaissance Orbiter, about 6,800 kilometers above the ground. NASA said Phobos approached Mars at a speed of 1.8 meters per century, which means that it will either hit Mars 50 million years later or be broken into a circle of debris.

Phobos has no atmosphere and it orbits Mars three times a day. NASA said that a popular theory is that it may be a captured asteroid, but some scientists dispute this. NASA added in the post that Phobos was discovered by the American astronomer Assaf Hall in 1877. According to NASA, in Greek mythology, Phobos and Phobos are the twin sons of Ares (Mars in Roman mythology).

In the title, NASA mentioned that “the image shows a pocked celestial body with a large impact basin called Stickney Crater. The grooves seen along its side may be tidal forces. The result-the mutual gravitation of the planet and the moon.”

Many Instagram users were shocked after seeing this photo.

User Ziggy Manzoni said: “It looks like it is made of some kind of metal.”

“It’s amazing! I have never seen it before,” Jobbe Pilgaard said.

American astronomer Asaph Hall discovered two moons of Mars in 1877. Hall named the two moons after the mythical son of Ares, the Greek counterpart of the Roman god Mars. Phobos, which means fear, is the brother of Deimos. This crater is named after his wife and mathematician Chloe Angeline Stickney Hall.

According to NASA, the day and night temperature measurements on Phobos showed extreme changes. It has a high temperature of -4 degrees Celsius and a low temperature of -112 degrees Celsius.

Scientists believe that this intense heat loss is probably the result of dust on the surface of Phobos, which is unable to retain heat.
