Fol. 87v: The diagram of the sun's orbit is shown as a circle within a larger circle oriented south at the top (דרום), entitled: “Image of the orbit of the sun which inclines from the zodiac sphere, and its centre does not coincide with the centre of the earth in its rise and descent” (צורת גלגל השמש הנוטה מגלגל המזלות, ואין נקודתו נקודת/ הארץ לרדת ולעלות ; Loewe 2004, II:672, 733).

The larger circle is inscribed four times: “zodiac sphere” (גלגל המזלות). The names of the twelve signs are written around the circumference clock-wise.                                                                                       

The inner circle is entitled on the right: “in the orbit of the sun” (בגלגל השמש) and inscribed in the centre: “centre of the orbit of the sun” (נקודות! גלגל השמש), and below it: “centre of the earth” (נקודות! הארץ).

The circles almost touch each other at the top marked: “A” south (א דרום:). The zodiacal position of each cardinal point is twice inscribed: for south, "mid-pointofGemini" ((חצי תאומים ; for west, "mid-pointofVirgo" ( חצי בתולה); for north, "mid-pointofSagitarius" (חצי קשת); for east, "mid-pointofPisces" (חצי דגים).

Inscribed diagonally within the inner circle, at the top point, south: "the (sun's) greatest height and farthermost distance" i.e. apogee (הגובה הגדול והמרחק הרחוק).                              

Opposite side, north: "the (sun's) least height and nearest distance" i.e. perigee (הקרוב  הגובה הקטן מרחק ).

Written twice on the right (west) and left (east): "median height" (הגובה האמצעי).
