In Jain Dharma, there is no traditional mapping of Tirthankars to planets.

Tirthankars are the 24 spiritual teachers who attained Keval Gyan and showed the path of liberation. They are not assigned to each planet in Jain scriptures.

The 24 Tirthankars are:

1. Rishabhdev
2. Ajitnath
3. Sambhavnath
4. Abhinandan Swami
5. Sumatinath
6. Padmaprabhu
7. Suparshvanath
8. Chandraprabhu
9. Pushpadanta
10. Shitalnath
11. Shreyanshnath
12. Vasupujya
13. Vimalnath
14. Anantanath
15. Dharmanath
16. Shantinath
17. Kunthunath
18. Aranath
19. Mallinath
20. Munisuvrat Swami
21. Naminath
22. Neminath
23. Parshvanath
24. Mahavir Swami

If you want, I can also give the 24 Tirthankars in order with their emblems and birth places.
