The term is also used to describe situations when all the planets are on the same side of the Sun although they are not necessarily in a straight line, such as on March 10, 1982. [8] Apparent planetary alignment involving Mercury, Venus, Mars, and Jupiter; the Moon is also shown, as the brightest object.
The last time all eight planets were aligned was on Dec. 28, 2022. On Jan. 18, 2025, there will be six planets in the alignment: Mercury, Mars, Jupiter, Uranus, Neptune and Saturn.
Mars, Jupiter, Uranus, Venus, Neptune, Mercury and Saturn will appear in a row on the evening of 28 February, marking the last time for 15 years that all of the planets will be visible at the same ...
The planets are always in a line known as the ecliptic, the plane where they orbit the Sun. As the planets race around the Sun at different speeds, sometimes they line up on the same side of the ...
A line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time. The square of a planet's orbital period is proportional to the cube of the length of the semi-major axis of its orbit. The elliptical orbits of planets were indicated by calculations of the orbit of Mars.
Because most orbits in the Solar System are nearly coplanar to the ecliptic, this occurs when the Sun, Earth, and the body are configured in an approximately straight line, or syzygy; that is, Earth and the body are in the same direction as seen from the Sun. Opposition occurs only for superior planets (see the diagram).
Catching a glimpse of the planets will depend on the time of day and their relative distance from the planet at the time. For example, Venus, Saturn and Jupiter are best viewed after sunset at ...
Larger planets make the dip in luminosity more noticeable and easier to detect. Followup observations using other methods are often carried out to ensure it is a planet. There are currently (December 2018) 2345 planets confirmed with Kepler light curves for stellar host. [7]
