Many people say that Varna is determined by birth, and others say Varna is determined by qualities. But I've seen some websites which claim that Varna is based on Rashi(our birth constellation/star). My question is, are there any scriptures which claim that Varna is determined by Rashi?
The Varna koota is factor in Vedic astrology which is used for match making purpose.
Four signs each are divided into 4 categories of a varna each.
Totally there are 8 such factors to be considered during match making which is called as Ashta Bhakoota.
There is also another section which is called "yoni" under which people are classified under yonis such as mooshaka, mahisha, sarpa, ashwa etc. Now this does not mean that the person will have characteristics like these animals. But it is just a classification for ascertaining the compatibility between two birth charts.
There are several factors used for this which includes graha maitri, nadi, vashya etc.
So one should not confuse this Varna with the actual varna of the person.
If this is to be considered then all those who are of libra, gemini, and aquarius sign are shudras irrespective of where they are born! Further, nowehere they consider the rashi during the upanayana ceremony for deciding the eligibility of the candidate.
Some of the famous examples of great saints who were born in these rashi are,
Sri Ramakrishna Paramahansa (Aquarius moon sign)
Ramanuja acharya (Gemini moon sign)
So this is just for matchmaking purpose and has NOTHING TO DO WITH THE ACTUAL VARNA.
According to Vedic astrology the varna is determined by the chandra rasis. Or it depends on where the moon was placed during the time of birth of a native.
There are four varnas- Brahmin, Kshatriya, Vaishya and Shudra.
Different natives, depending on the moon's placement in their natal charts, are assigned one of these four varnas as follows:
Varna -------> Moon signs
Brahmin ------> Cancer, Scorpio, Pisces.
Kshatriya --------> Aries, Leo, Sagitarius.
Vaishya ----------> Taurus, Virgo, Capricon.
Shudra -----------> Gemini, Libra, Aquarius.
The Brihat Parashara Hora Shastra mentions this as follows:
AQUARIUS DESCRIBED .' The sign Aquarius represents a man holding a pot. Its complexion is deep-brown. It has a medium build and a biped sign. It is very strong in day time. It resorts to deep water and is airy. It rises with its head and is Tamasic. It rules Sudras,the 4th Varna and the west. Its lord is Saturn,the Sun's offspring.
LIBRA AND SCORPIO DESCRIBED : Libra is a Seershodaya sign rising with its head and is strong in day time. It is black in complexion and is predominant with RaJoguna. It relates to tho western direction and resorts to land. It is destructive or mischievous. It represents Sudras or the 4th Varna and has a medium build and is a biped sign. Its lord is Venus. Scorpio has a slender physique and is a centipede sign. It denotes Brahmins and resides in holes. Its direction is north and is strong in day time. It is reddish-brown and resorts to water and land.

And, so on for the other rashis.
