A breif overview, neglecting some of the significations such as health and father. Mars is ruled by Aries and Sun is friendly to this planet. Thus we have a Mars-Sun (warrior-king) combination which gives action that is motivated by righteous inclinations, the desire to rise in onessphere and an abundance of strength. The direction and pathway in ones life will be clear and unambiguous and the native will endure on this route with intense motivation and strong sense of what is right and what is wrong. Therefore this native will inspire those around him and have natural leadership traits. This may detract from domestic life where commitments will be regarded as unnecessarydistractions and annoyances, and where one will cut an overly authorititive and dominating figure . In relationships especially, asthe Sun will cast a powerful and direct aspect on Libra, the sign ofrelationships/marriage and Sun`s debilitation. This will inhibit the ability to reconcile and compromise, and will add a natural sharp coating to the personality. Hence popularity may not be extreme but the native will be respected more out of fear and due to his power.An additional insight is that Aries is the sign that debilitates the humble Saturn, the planet of hardwork, and the very fact that Aries exalts a royal planet such as the Sun indicates that the nature will be to command and lead rather than toil to any great extent. It can thus be deduced that success will come with relative ease, due to the adoption of a highly efficient strategy, fully in tune with ones strengths. Sun in Aries provides a set-up via which one can focus on ones self and abide by ones duties in accordance with his inherent principles.
