For example, if we could see the stars during the day, we would notice that in late March and early April, the constellation Pisces the Fish is on the other side of the sun. For instance, the Astronomical Almanac[27] lists the heliocentric position of Mars at 0h Terrestrial Time, 4 January 2010 as: longitude 1180915.8, latitude +14316.7, true heliocentric distance 1.6302454 AU, mean equinox and ecliptic of date. This angle is called the obliquity of the ecliptic, or axial tilt.
