हत्वा पृथक्शीघ्रकर्णव्यासयोगेन भाजितम् ।
कर्णे हीनेऽधिके स्वर्ण कुर्याद् बिम्बे स्फुटं भवेत् ।
[Translation. 45 severally divided by 17, 13, 11, 9, and 15
are the mean diameters (in minutes of arc) of the planets
beginning with Marऽ (*.e., of Mars, Mercury.Jupiter, Venus,
and Saturn). Each diameter should be multiplied by the diffe
rence between the ॐghra-kar70 and the radius and then divided
by the sum of the ॐgh70-5ar70 and the radius ; and whatever is
obtaimed should. be added to or subtracted from the mean
diameter, according as the ॐgra-kar10 is less or greater (than the
radius '. Thus are obtained the true diameters ( in minutes
of arc).]]
These two verses do not belong to the text because their
contents are not in conformity with the teachings of Bhaskara I
The first of the two verses gives the mean diameters of the
planets which are different from those given in the Mahā
Bhaskary0 both in absolute and relative magnitudes as is clear
from the following table :
Planet
Mercury
Jupiter
Venus
