  Although previous searches for star clusters have been very successful, many
clusters are likely still omitted, especially at high Galactic latitude
regions. In this work, based on the astrometry of Gaia EDR3, we searched nearby
(parallax > 0.8 mas) all-sky regions, obtaining 886 star clusters, of which 270
candidates have not been cataloged before. At the same time, we have presented
the physical parameters of the clusters by fitting theoretical isochrones to
their optical magnitudes. More halo members and expanding structures in many
star clusters were also found. Most of the new objects are young clusters that
are less than 100 million years old. Our work greatly increased the sample size
and physical parameters of star clusters in the solar neighborhood, in
particular, 46 clusters are newly found with |b| > 20 deg, which represents an
increase of nearly three fold of cluster numbers at high Galactic latitude
regions. The cluster parameters and member stars are available at CDS via
https://cdsarc.u-strasbg.fr/ftp/vizier.submit//hezh22b/, and the cluster figure
sets are available via https://doi.org/10.12149/101133.
