It is propagated by Eurocentricists that the Weekday Sequence was derived from Planetary Distances from Earth by Chaldeans, because Greeks learnt astrology and astronomy from the Chaldeans. But it is a false view. The following picture shows the correct view :-
In this picture, starting from the nearest Graha Moon (Soma or Chandra) and moving clockwise, we find the Weekday Sequence, ending at the farthest Graha Shani beyond which is Bha-chakra or circle of Nakshatras at a distance of 60 years of orbit. Larger orbits belong to stars and dhooma-ketus, not to be regarded as Grahas. This is traditional Indian view. Modern science defines planets in terms of orbits around the Sun with size more than Pluto. This modern definition of Grahas is qualitatively quite different from the ancient Indian definition of Grahas which were defined as deities, as incarnations of God giving fruits of past karmas to jeevas through astrology.
By skipping one Graha in the Weekday-sequence of this picture, we get the sequence of Planetary Distances measured from Earth, which are shown in red lines.
Horizontal green lines show the different Lokas according to Vedic-Purānic view : at the top is Pitr-Loka of Moon, then we find Sun-plus-Mars which depict Martya-loka according to BPHS (Brihat-Parāhsara-Horā-Shāstra), then we find Saturn-plus-Mercury which denote Naraka-loka according to BPHS, and lastly we find Venus and Jupiter which denote Deva-loka according to BPHS.
Rishi Parāshara also stated in BPHS that he added nothing in his text and repeated the ideas of earlier masters only. Hence, this view also comes from the earlierst Vedic rishis.
Therefore, deducing Weekday-sequence from Planetary-distances is the wrong and reversed method, and requires jumps over two planets, whereas this Indian view needs jump on one Graha only and is in tune with canonical view about different Lokas too.
BPHS regards Moon also a part of lower realm of Devaloka. Hence, there are three tiers in Heaven : Pitr-loka (Chandra), Karma-devaloka (Shukra) and Äajāna-devaloka (Brihaspati). Pirt-loka is the unseen side of non-material Moon of Bhuvaloka which is never visible from Earth, Karma-devaloka is that loka where jeevas enjoy temporary Heaven according to their karmas but do not enjoy company of immortal deities and deities like Indra are also Karmadevas (one Indra is for one Manvantara, after which another Jeeva gets that post for next Manvantara), while Äajāna-devaloka is that highest loka where jeevas enjoy temporary Heaven according to their karmas and also enjoy company of immortal deities like Suryadeva.
How the jeevas go to different lokas after death is described in BPHS. While judging a horoscope, I secretly examine this trait first of all, which gives me an idea of overall virtue/sin of the native. A person going to Hell is not worthy of astrological assistance unless the native is ready to undergo excruciating tapasyā which is unlikely, such natives will not accept that they have committed grave sins.
Planetary distances are secondary, they are created after the Creation. But the above scheme precedes the Creation, it is part of Vedic Knowledge of rishis which is eternal and according to which all Kalpas are createwd according to previous Kalpas (cf. last line of Aghamarshana Sookta of Rgveda).
