The stars with exoplanets are not equally distributed among the 88 astronomical constellations. Exoplanets detections are slightly more biased toward the northern hemisphere and the sky area covered by each constellation is not equal. Many fall within the well known 12 zodiac constellations of the ecliptic that are associated with the astrological signs (Figure and Table 1). The night sky is full with over 600 stars with confirmed exoplanets (Figure and Table 2) but only around 71 of those stars are visible to the naked eye (Figure and Table 3). Only the stars are visible and EXOPLANETS ARE TOO DIM TO BE VISIBLE IN ANY CASE. This page is part of an educational project for star parties to learn and observe the constellations and stars with exoplanets. You can plan your observation night using free software like Celestia or Stellarium, an online sky map, or a mobile app like Sky Map to locate the constellations and the stars listed in the figures and tables below (use the search feature by star name of each program). If you are an amateur astronomer really into observing exoplanets then you should visit the Exoplanet Transit Database and check the book Exoplanet Observing for Amateurs: 2nd Edition (a free online version is available).

Figure 2. Location of over 600 stars with over 800 confirmed exoplanets (some stars have multiple planets). This plot provides a general sense of the distribution of these stars. It those not necessarily has the resolution for their accurate identification in the night sky but use a star chart software instead. Click the image for a better resolution version.

Table 2. List of constellations with their number of stars that have planets and total number of planets. Zodiac constellations are indicated with an asterisk. This list can be used together with a list of planet and star properties (i.e. HEC-FDE) to plan educational observations. Some stars are even visible with the naked eye (see Table 3). The constellation of Eridanus has more naked-eye visible stars with planets.

The parenthesis shows the large number of stars with exoplanets candidates in each constellation (as of September 2012) but none are visible with the naked eye.
Figure 3. Location of the 34 naked-eye visible stars (down to magnitude 4) with confirmed exoplanets (some stars have multiple planets). A star chart software is also recommended to identify these stars in the night sky such as Sky Map App for Android (a cloned free version with the same name is also available for iOS, not as good).

Table 3. List of the 71 naked-eye visible stars with confirmed exoplanets down to magnitude 6, which requires a clear and dark night outside of city lights for observations. The list is sorted by constellation name. The brightest star with an exoplanet is HD 62509, better known as Pollux in the Gemini constellation.
