A "Manunder Object" could be a sunspot occurring during the Maunder Minimum.
The Maunder Minimum is the name given to the period roughly spanning 1645 to 1715 by John A. Eddy in a landmark 1976 paper published in Science titled "The Maunder Minimum", when sunspots became exceedingly rare, as noted by solar observers of the time. Astronomers before Eddy had also named the period after the solar astronomer Edward W. Maunder (1851-1928) who studied how sunspot latitudes changed with time.
The Maunder Minimum, also known as the "prolonged sunspot minimum", is the name used for the period starting in about 1645 and continuing to about 1715 when sunspots became exceedingly rare, as noted by solar observers of the time.
The greatest number of sunspots during the period from 1700 to 1800 was observed around the year 1778. The peak sunspot activity during this time is known as the "Maunder Maximum," a period of high solar activity.
The mass of an object doesn't depend on the gravitational force on the object.
[object Object]
The center of mass of an object is the point at which its mass can be considered to be concentrated. It is the average position of all the mass in the object. It is the point around which the object will balance in any orientation.
