The sky in April 2017

Summary: Venus has now moved into the morning sky and rapidly draws away from the Sun. Jupiter now rises in the early evening, with Saturn rising later in the night.

The planets

mercurythmMercury may be found low in the west after sunset in the first week of April if you have a clear, unobstructed horizon. But it sinks rapidly back to reach inferior conjunction on the 19th, when it will lie between us and the Sun.

venusthmVenus moved into the morning sky at the end of March and now climbs rapidly above the eastern horizon as the month progresses. Through a telescope it will appear as a fine crescent. The planet shines at a brilliant -4.7 magnitude by the month’s end.

marsthmMars is still hanging on in the evening sky, shining like a bright star. The planet is receding on the far side of the Sun now and its brightness fades from magnitude 1.3 to 1.5 during the month.

jupiterthmJupiter, the biggest planet in the Solar System, is very well placed, rising in the mid evening. Find it in the constellation of Virgo, not far from its brightest star, Spica, using our helpful guide. The planet shines at around -2.5, making it the brightest object in the sky after the Moon and Venus. A small telescope will reveal the planet’s belts and bands as well as the four main moons, known as the Galilean satellites, Io, Europa, Ganymede and Callisto.




saturnthmSaturn lies in the morning sky this month, rising in the late evening at the beginning of April but two hours earlier by month’s end. To the naked eye, it resembles a bright yellow star at magnitude 0.5. A small telescope will show its rings are wide open, making it an attractive sight.

uranus_thmUranus has been lost to view in the evening twilight.

neptune_thmNeptune the last of the eight worlds recognised as planets in our Solar System, is in the morning sky, but lost in pre-dawn twilight.
