Question

Which planet looks reddish in the night sky?
(A) Mars
(B) Saturn
(C) Jupiter
(D) Mercury

Answer 1

Hint: A planet is a cosmological body circling a star or astral residue that is gigantic enough to be curved by its own gravity, is not gigantic enough to instigate thermonuclear synthesis, and – rendering to the International Astronomical Union but not all terrestrial researchers – has cleared its adjoining area of planetesimals.

Complete answer:
Mars is the 4th planet from the Sun and the second-smallest planet in the Solar System, being larger than just Mercury. In English, Mars conveys the name of the Roman god of war and is frequently denoted as the "Red Planet". The latter denotes the product of the iron oxide ubiquitous on Mars's exterior, which gives it a reddish look distinguishing amongst the cosmological bodies perceptible to the naked eye. Mars is a telluric planet with a thin atmosphere, with exterior characteristics suggestive of the power craters of the Moon and the gorges, deserts and polar ice caps of Earth. Mars can simply be seen from Earth with the naked eye, as can its reddish shading. Its outward size reaches −2.94, which is exceeded only by Venus, the Moon and the Sun. Optical ground-based telescopes are usually restricted to determining characteristics about 300 km (190 mi) across when Earth and Mars are nearby because of Earth's atmosphere.

Thus, option (A) is correct.

Note: The history of explanations of Mars is noticeable by the obstructions of Mars, when the planet is nearby to Earth and thus is most effortlessly noticeable, which transpire every couple of years. Even more distinguished are the perihelic obstructions of Mars, which transpire every 15 or 17 years and are eminent because Mars is adjacent to perihelion, making it even nearer to Earth.
