A Good Time to Observe Dwarf Planet Makemake
On March 29, we have a great opportunity to observe the dwarf planet Makemake. It will be at opposition, which means it will reach the highest point in the sky at around midnight and be opposite to the Sun. At around the same time Makemake will also reach its closest point to the Earth (perigee) at a distance of 51.77 AU. Its peak brightness will be an apparent magnitude of 17.1, which makes it the brightest trans-Neptunian object after Pluto.
Stargazing Calendar for March 2023
Hello fellow stargazers! This month we only have one small meteor shower, but instead we can look forward to a comet visiting the inner solar system (just barely) and more interestingly two dwarf planets at opposition - Ceres and Makemake.
Monthly Stargazing Calendar for July 2015
On July 14 NASA's New Horizons spacecraft is scheduled to arrive at Pluto after a nine and a half year journey. It was launched on January 19, 2006 and will be the first spacecraft to visit Pluto. New Horizons will give us our first close-up views of the dwarf planet and its moons.
The Solar System To Scale [Infographic]
The following is a huge infographic showing the true scale of the solar system with all its planets, minor bodies and the most famous probes we have sent out into deep space. Scientists measure distances in our solar system in astronomical units (AU).
