- M-type star (Wikipedia)
Class M stars are by far the most common. About 76% of the main-sequence stars in the solar neighborhood are class M stars. However, class M main-sequence stars (red dwarfs) have such low luminosities that none are bright enough to be seen with the unaided eye, unless under exceptional conditions. The brightest-known M class main-sequence star is Lacaille 8760, class M0V, with magnitude 6.7 (the limiting magnitude for typical naked-eye visibility under good conditions being typically quoted as 6.5), and it is extremely unlikely that any brighter examples will be found.
- Ecclesiastes (Wikipedia)
Ecclesiastes (/ɪˌkliːziˈæstiːz/, ih-KLEE-zee-ASS-teez; Biblical Hebrew: קֹהֶלֶת, romanized: Qōheleṯ, Ancient Greek: Ἐκκλησιαστής, romanized: Ekklēsiastēs) is one of the Ketuvim (“Writings”) of the Hebrew Bible and part of the Wisdom literature of the Christian Old Testament. The title commonly used in English is a Latin transliteration of the Greek translation of the Hebrew word קֹהֶלֶת (Kohelet, Koheleth, Qoheleth or Qohelet). An unnamed author introduces “The words of Kohelet, son of David, king in Jerusalem” (1:1) and does not use his own voice again until the final verses (12:9–14), where he gives his own thoughts and summarises the statements of Kohelet; the main body of the text is ascribed to Kohelet himself.
