Yes, you can! The Navagraha temples are in Tamil Nadu and are about 100 Km apart in total. If you set out early, you can see them all in one day by car. Start your trip either from Kumbakonam or Thanjavur, and make your first stop at Thingaloor Chandran or Moon temple. After that, you can head to the other temples, finishing up at Thirunallaru Sani Temple in the evening.
