When is the best day to see Comet Nishimura in Spain, a “phenomenon” that will not be seen for 434 years?

Last August, exactly on the 12th, the Japanese scientistHideo Nishimuradiscovered a new “phenomenon” in the sky: Comet Nishimurawhat can be seen in Spain these days, but there is an exceptional day that will be unique to see it better. A comet that, according to experts, we will only see after 434 years.

The best day to enjoy all its splendor is dusk. Sunday September 17th. “In recent days the comet has been visible at dawn, but before sunrise at a very low altitude above the eastern horizon,” he said in statements to EFE. Miguel Querejet, astronomer at the National Astronomical Observatory (OAN).

But starting today, Wednesday, September 13, “the comet begins to become visible at dusk, at a very low altitude above the western horizon, moving from the constellation Leo toward the constellation Virgo,” the researcher says.

Technically, the comet is known as C/2023 P1 and was named Nishimura in honor of the amateur astronomer who discovered it. This comet is located about 125 million kilometers away and continues to approach the Sun, so its brightness will gradually increase over the course of this week.

According to calculations by NASA’s Jet Propulsion Laboratory, Nishimura will be just 34 million kilometers from the Sun on Sunday, September 17. On this day it will reach perihelion, when it reaches its minimum distance from the Sun.

“At this point it is exceedingly difficult or almost impossible to observe it with the naked eye, as its faint glow is lost in the glow of dawn,” but “it is possible for the comet to be seen with the naked eye, albeit with ” It was a big challenge at the end of this week,” explains Querejeta.

Comets are amalgams of small fine dust particles (residual minerals from the formation of the solar system) plus a portion of ice, as well as water, methane and ammonia and other compounds as well as organic substances.
