All goddesses were supposed to be more beautiful than mortal women, so yes.
Yes, they are half siblings. Zeus is the father of all of them, but Athena has a different mother than Apollo and Artemis. Athena's mother is Metis, while the mother of Apollo and Artemis is Leto.
Athena and Artemis were half sisters, both being daughters of Zeus. They are not known to have loved each other as anything other than sisters.
Artemis did not have a husband, as she was a virgin goddess. The three virgin goddesses were Artemis, Athena, and Hestia. Artemis protected her virginity more fiercely than the others. Athena and Hestia did not hate men, but Artemis despised them.
"To the fairest" was given to Aphrodite by Paris, for judging that she was even more beautiful/fair than Hera or Athena.
Hera, Hestia, Demeter, Artemis, Persephone,...
Artemis and Hestia.
No, Artemis was his only direct sibling. Since he is the son of Zeus, he would have many half sisters like Athena and Helen.
Her father is Zeus and her mother is Leto. She has a twin brother named Apollo. Her grandfathers are Cronos and Coeus. Her grandmothers are Rhea and Phoebe. Her uncles are Poseidon and Hades. Her aunts are Hera, Demeter, and Hestia. Since all the gods are related, she has a very large extended family.
Artemis her twin brother Apollo, Ares, Zeus, Aphrodite, Hermes, Poseidon, Hades
No, the only children of Leto and Zeus are Artemis and Apollo. If you want to go half siblings, she has a lot because of Zeus. Some of them would be Athena, Ares, Hephaestus, Hermes, Persephone, Dionysus, Hercules, Perseus, Helen, and many more.
She was a beautiful girl and weaves very well, but she boasted that she weaves better than Athena, the goddess of the loom, so Athena turned her into a spider.
